Apple's privacy labels show WhatsApp and Facebook Messenger hunger for user data (techradar.com)

In other news, google apps still don't have a privacy label:

https://www.macrumors.com/2021/01/05/google-hasnt-updated-io...

I really wonder why :)

And apparently iMessage has a privacy statement now, and it's much shorter than whatsapp's:

(This is posted on HN too).


iMessage is shorter because Apple already uses the OS for data collection and can easily match your id:

https://support.apple.com/en-us/HT205223


I'm curious: if Facebook did exactly what Apple describes in this document for its WhatsApp customers (at least for data beyond the minimum required to deliver their service), would their privacy statement be able to look like iMessage's? I'm guessing not, but I wonder if someone who is more knowledgeable could answer the question definitively.


Shows you how much the OS and various services inside the OS need privacy labels and affirmative consent too.


Exactly. I've generally not been excited about the idea of industrial policy targeting OSes beyond App Store limitations, but at this point I feel pretty strongly about its need. The absurdity of this is getting a wee bit out of hand.


I wonder...

If they don't update the apps, do they have to update the privacy policy?


That's the idea. New submissions have to include the privacy label, be them new apps or updates to old apps.

Whatever's already submitted stays like that.


> I really wonder why :)

No big mystery there.

> iMessage has a privacy statement now, and it's much shorter than whatsapp's

Or there.

I wonder how effective these things really will be. Most people aren't going to scroll through these so the average person is going to ignore the everything below the fold. It's like the required disclaimers on medicines which people ignore. Once you get past the first few, nobody pays attention.


It doesn't have to have an effect to everyone, it's about taking responsibility and actually defining what they're doing.

Once we have everyone actually publishing what they're doing it's a lot simpler to file complaints to DPA's and to verify they're actually compliant with legislation.


It's really hard to tell with Facebook if they understand that their massive data collection is at least morally questionable, and they business plan is simply a calculated risk. Given that most people seem to care more about free services, than they do about privacy, Facebook may see privacy labelling is a pointless exercise that won't change anything anyway.

Or perhaps we are back at Upton Sinclair: "It is difficult to get a man to understand something, when his salary depends on his not understanding it." and Facebook as an organisation is simply unable to acknowledge the problem, because doing so would ruin them.


If Facebook charged 2$ a month for their services, would they not make more than their operational costs? They choose to exploit and straddle areas that are morally and legally dubious because they want more money.


They'd lose many users. $2 a month might not be a lot, but any non-zero amount of money is a barrier for users. On one side some users might not have an easy way to pay, others will still have to reconsider whether Facebook itself offers enough to be worth the $2 a month (even if it totally does).

Also, a more likely outcome would be Facebook charging $2 a month on top of their usual data collection practices.


That's really the scary part, most people wouldn't pay $2 per month for Facebook. Most wouldn't pay the $1 for WhatsApp. That shows you how little value these services actually provide to most people. The remaining users wouldn't pay for year two, because to many others would have left the platform.


Most wouldn't pay because there are alternative free services with a somewhat similar model. This analysis would be more interesting if all these 'free' alternatives go away.


>That shows you how little value these services actually provide to most people. The remaining users wouldn't pay for year two, because to many others would have left the platform.

No, I'm extremely critical of many aspects of Facebook (and implicitly Whatsapp as an FB property, especially now) but to say they provide so little value based on how few people would possibly pay these amounts uses flawed assumptions. If people didn't pay it wouldn't be because they don't gain at least 1 or 2 dollars in value (many people almost certainly do, I certainly do with my own use), it would be because the model of offering high value for free in exchange for massive amounts of saleable user data is so lucrative that alternatives with free versions would quickly take over market share. In absolute terms, the use value of FB or Whatsapp to a user is often much more than 1 dollar per month, but compared to the ease of switching to someone who in the existing market again offers the same for free, it could quickly descend to less than 1 dollar.


It's not just Facebook and WhatsApp, it's pretty much any service we've become accustomed to getting for 'nothing'. As a comparison, I run the domain my family uses for e-mail (not just my spouse/kids, but my brothers and parents and a few extended family members as well), and it's currently hosted on GSuite, grandfathered in from way back when you could get it free. I wanted to switch us away from Google to FastMail, but everyone balked at $5/month for e-mail. Even the ones making well into six figures didn't want to cough up $60/year for something they've been getting for free. So I could pay it out of pocket, or we stay on GSuite, or I kick everyone off that won't pay and deal with hurt feelings.


Didn't WhatsApp actually cost like 1 EUR/year before FB bought it?


It did, first year free, then $1 per year, but I think many just created a new account, or WhatsApp perhaps didn't really enforce the payment much.


I think it was highly profitable business because before FB acquisition it was very small company (~100 people) compared to user base (hundreds of milions). but FB did acquisition not because of profits but because of userbase to collect more data. So to increase userbase even more, FB got rid of payment plans and made service for free.

Edit: tried to google concrete numbers what revenue was back then, could not find any clear answer, because it was doing some juggling with stocks etc. https://techcrunch.com/2014/10/28/whatsapp-revenue/


Yep, first year free, then $1 payment, but if you wanted, you could just uninstall, reinstall and it would reset the entire schedule. Acton and Koum really wanted it to be something different than what it is now.


IIRC I even bought the app on the app store and then had some kind of "lifetime" plan, easier times


as far as I remember - yes, it was 1 dollar/euro per year after first year for free.


I think most people do manage to get at least a buck or two's worth (adjusted for local purchasing power) of use out of WhatsApp (if not facebook.com); surely, the ability to instantly contact people via text/call/video must be more useful than music streaming?

The problem seems to be that if competing services remain free, then users might start questioning the fee and eventually the base might migrate.

Really, while "free" internet services appear as if they are straight out of a post-work utopia, all they seem to be doing is trivializing the social cost of accurate and insidious targeting of groups jazzed up in sexy terms like "digital marketing" and "adtech".


People using WhatsApp are holding a cellphone, so it’s not about suddenly being able to communicate with people.


Holding a cellphone is step 1; step 2 is having a tool that can facilitate frictionless communication to one or more people -- easy and cheap enough for pretty much any demographic to grasp. Contacting someone from what was essentially a portable landline is surely very different from using WhatsApp (or any chat application) on a modern smartphone?


> People using WhatsApp are holding a cellphone

Have you actually used cellphones? They're extremely expensive to actually communicate with, especially in the countries where WhatsApp is near ubiquitous (and we're talking within country, let's not even get into how horrendously expensive communicating with people internationally can be via regular cell service).

I really don't understand why so many people on HN are this adamant about trivialising the value that apps like Whatsapp provide.


WhatsApp adoption clearly demonstrates they are providing value to people. My point is people are looking at what the app does rather than why people use it. Phone conferences for example have been a thing for decades, but they weren’t free.


Most people wouldn’t pay but some would pay a lot, in the form of donations.

I can easily envision a world where Facebook was a nonprofit along the lines of Wikipedia. Ad-free and supported by donations, the site would serve to connect the world (Facebook’s ostensible mission) without resorting to dark patterns or A/B testing for addictive engagement. I think there are plenty of wealthy people out there who would love to support such a site, if it existed.

Technology-wise, such a site could be built today, no problem. I have no idea what to do about the network effects that comprise Facebook’s moat, however.


So a company that, in your own words, uses dark patterns and addictive engagement, could possibly be this [rose-tinted glasses conception of] Wikipedia? That’s ridiculous. That’s not even alternative history as you are reimagining the whole foundation of the company.

Really, this must come from some utopian idea that company-founders really want to make the world better above else, but then profit-seeking—the modus operandi of all for-profit companies—intervenes just because the world is not pure enough for their vision.


> Most wouldn't pay the $1 for WhatsApp. That shows you how little value these services actually provide

Most people don’t pay for air, therefore those people would be happy if their access to air was removed?


> Most wouldn't pay the $1 for WhatsApp.

It had explosive growth despite (or to some degree because of) the yearly $1 fee.

I'd happily also paid for my kids and a number of my friends to keep them on old WhatsApp, pre-Facebook, if they needed it.

Instead they sold out.


What would be interesting if they offered an ad free option - like Amazon Kindle, youtube etc.

Back of the envelope calculation suggests they make about $2 a month from each user (~$70B revenue/year divided by ~2.7B active users/month)


I would love this if I trusted any online service to maintain the paid option as truly ad-free over time but I've been burned by the TV industry too many times. Ad creep ruins every paid service and ultimately just drives the price up.


* Offering an ad-free version devalues their ad network so it would end up being more tha $2/mo.

* Even if they didn't show you ads they have no reason to not still obsessively track you and monetize that data in other ways.


Yes, but if they continue to hemorrhage users they may come to wish they were making $2/user.

Long term, Facebook is dead. Perhaps internally they know that and are already planning for it.


This is kind of my point, too. Free market will incentivize getting money both ways so without regulation, this is what we get. And I hate it.


Sounds like cheaper version of linkedin.


I don't value Facebook at $2 a month, I bet most people don't either.


A family member recently relayed the story of his kid begging for $20 for a “bunny suit” Fortnight skin and how he, the adult, slowly came to understand that the skin didn’t even do anything; it just ever-so-slightly changed how the game looked (which I already knew, but his exasperation was amusing). We were like, huh. Kids today.

Anyway, for reasons I don’t totally understand, in my experience this dad’s bunny-suit exasperation is how most people feel about paying for software of any kind. It’s not just frugality but indignation at the very idea that they be asked to pay for software.


Yeah, these kids today wanting to pay for things that change their appearance in the world where they interact with their friends.

I really don't get this. Did you never buy a ringtone for your phone because you thought it was cool? Or some item of clothing that didn't serve a purely functional purpose. Do you not have any art or photos on your wall? I assume you still have your default desktop wallpaper and phone background.

Like I live my life surrounded by all sorts of random junk that brings me joy. How can you not?


I meant it to be an amusing anecdote about someone being confounded by something outside their realm of culture, not a critique of young people or Fortnight or even of digital bunny suits (though I admit $20 does seem expensive for a digital bunny suit). I meant no offense. Surely there's some cultural phenomena (truck nuts? Haunted dolls? Calvin peeing? Beanie Babies? VSCO girls?) that makes you think, huh, that's a thing that I don't quite get? That's all I meant to convey.


What does a real world bunny suit do that a Fortnite bunny suit doesn't?


For one, you own it - so you can sell it when it’s no longer amusing.


Do you mean to say there is a market for used bunny suits? I think 'jpttsn might have a point specifically with respect to useless nonsense products.


Whether or not anyone wants to purchase is a separate concern from the fact of ownership.

Edit: there are approx. 1000 used bunny suits for sale on EBay, so...


If you check the "completed listing" box, most of the ones that sell seem to be doll clothing or other collectables. Half of the human clothing listings that sold are skiing "bunny suits" https://www.ebay.com/sch/i.html?_from=R40&_nkw=bunny+suit&_s...


Besides you owning a physical product:

1 - if it's like a Kigurumi (pajama), you can wear at home during winter, looking good/cute

2 - If you are female (can apply to males to maybe), Wear and post photos on instagram/twitter, make Only Fans/Patreon sets to make money

3 - if it flows your boat, wear during... you know...


1, 2 seem doable with the Fortnite bunny suit

I agree on 3, parents should get the kids real brick and mortar sex toys instead of the virtual DLC.


How's a Fortnite item actually keep you warm in winter? You would be naked if the choice was actual pajamas vs game item


I think the feeling of something tangible (ie takes physical resources to create it) is a big driver of it. In a sense its own vs lease.

I have met people who refuse to pay for digital music but have zero qualms buying records. Arguably the records have less use cases but they are YOURS and tangible.


TERRIFY CHILDREN


Facebook made approximately $30 (USD) per user in advertising revenue last year. I think the bigger issue (IMHO) is that the people who are prepared to pay to not be profiled are the people who are the most valuable to advertise to. i.e. they are worth way more than $30 in revenue per year.


On the other hand, the people willing to pay to not be profiled are probably already using adblockers and piholes everywhere they can, no?


Facebook is relatively immune to ad blockers as most Facebook, WhatsApp & Instagram usage is mobile (and why Instagram's web version is very bare-bones and lacks critical functionality).


That's fair. I'm still using Firefox mobile with adblocking, so I didn't consider that.


Facebook grosses about $22/user/year from their platform.

If all users paid $2/month they’d be fine.

Problem is, not many people would shell out $2/month to socialize online.


Also, let's say I'm willing to pay $2 to use facebook and socialize with my friends. If 2 or 3 close(-ish) friends drop off because of that, facebook would no longer be worth $2, so I would also drop off


Well, you can't undelete data you didn't collect. So I think there's this natural tendency toward omnivorous data collection in every tech company.

Then we rationalize it by telling ourselves that we use it ethically. It's almost always true . . . except when it's not. If 99% of the time the data is used ethically, it's easy to write off that 1% even when the 1% is all that matters.


> Given that most people seem to care more about free services, than they do about privacy,

What a backwards analysis.

A social platform that is not already popular is worthless to most people. They have no use for it. Hence they are definitely unwilling to pay for it before it gets popular; there is absolutely no incentive to. And, of course, once a social media platform _already_ is popular, it must have gotten to that point by operating at a loss.


If they can’t manage to charge $1 per user per month for their service then perhaps their service isn’t worth anything at all.


I am all for bashing Facebook, but comments like this don't help us come across as thoughtful in our criticism. The question is not if they could run their business with an ARPU of $1.00, but instead why would they do so if they are able to achieve an ARPU of $39.63 (Q3 2020).

Most companies in this world choose not to willingly leave money on the table, and Facebook is simply taking the same position as millions of other businesses. The only way to get them to earn less than they could is by forcing them to do so through market forces (eg: iOS 14) or regulation.


I would be happy to pay $39.63 to remove ads and allow me to browse FB without all my usage history and personal info getting sold to the highest bidder, but they don’t even give that option. So, I hardly ever use it.


By that logic, is Wikipedia perhaps not worth anything at all? Monthly user subscriptions is not the only way to determine value.


Wikipedia is supported entirely by donations. I would hazard a guess that people who donate to Wikipedia consider it to be worth the money they choose to donate, and more.


So, mostly worthless to the overwhelming majority of people who don't donate, and even more who donate less than the equivalent of $1/user/month? I'm aware that Wikipedia is supported by donations, that doesn't change the fact that Wikipedia is immensely valuable to many people even though they apparently can't manage to charge $1 per user per month for their service. In many ways, Wikipedia is so valuable because they don't charge their users.


A lot of people in Canada don't pay anything for their health care and don't pay taxes either because they don't earn any income. I don't think it is reasonable to suggest these people think their health care is "worthless."

The mistake here is conflating price with value. The price people are willing to pay is relative to their means. The value, on the other hand, is relative to the utility they derive from it. Moreover, there is an additional external utility accrued to society from having a better educated, healthier population.


Sure, that's exactly my point, I don't think it's reasonable to suggest that Facebook is worthless because they won't or can't charge their users just like healthcare isn't worthless because many people don't directly pay for it.


> I don't think it is reasonable to suggest these people think their health care is "worthless."

That was literally OP's point.


Then all (citation needed) search engines are not worth, as they are free. HN and wikipedia are also completely worthless.


Tell that to FB and Linkedin's valuations.


And WeWork was worth $47 billion at peak. So?


It's not hard. Clearly the understand. Their M.O. is predictable to a fault. These are not accidents.

This should help. I immediately bought the book.

https://www.wnycstudios.org/podcasts/otm/segments/living-und...


I think you ascribe far to much skill and control to a company that clearly has little to no coordination.


Of the entire FAANG lineup, Facebook has the simplest chain of responsibility. Mark Zuckerberg is not only the CEO but owns a majority of voting shares. If he decided tomorrow that Facebook should prioritize user privacy, he could make it happen. Who's going to stop him? It's weird to describe this kind of corporate structure as one that has "little to no coordination".


I mean thats literally what he's doing now.

the point is, no one believes him, or really listens to him.

Its not Amazon where Bezos commands, and everyone jumps.


Perhaps. But there is a common ends (i.e., profitting from data collection) and common means (i.e., Privacy? What's that??).

There doesn't have to internal coordination any more than FB has to coordinate with (e.g.) Google. Priorities drive action.


iMessage seems to be a bit dishonest, because Apple, the owner, has way more information about you through iCloud and Apple ID - contacts, location, payment data, phone number, etc.

Forcing Facebook to clearly list all of this for the facebook account is great, but then failing to disclose this for their own account seems like double standard.

Just like having their own separate Ad Tracking switch which is on by default. (And even hidden under "System Services" on macOS!)


On iOS your location data, as far as Apple has it, is not associated with you or your device but with an identifier that is changed weekly.

If you choose to use iCloud to store your contacts (and you can choose any other service that implements the carddav standard) Apple declares the information is transmitted and stored encrypted and can’t be used for any other purpose.

https://support.apple.com/en-us/HT202303


Apple shares iCloud backups with law enforcement.


If you read the document, it has a list of types of data protected by end-to-end encryption, which no one but yourself has access to. This list does not include iCloud backups.

If you do not want this to happen, do not turn on the optional iCloud backups.

But anyway, although Apple could decrypt the other data, they declare they don’t. Which is what the labels are about.


It also does not contain iCloud Photos. Nor iCloud Drive. For that matter, apple can intercept and MITM iMessage when requested by the government and don’t allow you to verify the key unlike, say, Signal or WhatsApp. I mean it’s available in China for a reason.


If it's truly end to end encryption it can't be MITM. However it could be required to be intercepted ETE in China


You never get to verify that they key you’re signing with matches the key on your correspondent’s device. You are trusting Apple with it, and they could be compelled to MITM your future conversations. This is in contrast with, say, Signal, where you do get to compare keys (and it’s open source with reproducible builds).


If it’s end-to-end encrypted, why would intercepting the message be an issue?


MITMing future messages could be completely transparent to the user.


I don't get this take. Your bank, employer, ISP, pretty much any tech company, etc. would also share your data with law enforcement if court ordered.


Of course and that's constantly being brought out as a huge negative when talking about Google, Facebook, Microsoft data storage. It also needs to be clearly said for Apple as well and not just swiped under the rug underneath corporate marketing.


Of course and that's constantly being brought out as a huge negative when talking about Google, Facebook, Microsoft data storage

No, what is constantly being brought out as a huge negative when talking about Google and Facebook is them using your data and data about you to make money.


Yes, it’s brought out as a negative because those companies are actively using that data to influence your behavior and serve you ads. Apple does not do this.


except apple has the tech to not be able to share it. they use this for some of your data. but intentionally not for icloud.

it’s probably nothing to do with USA law enforcement. my reasonable guess is they don’t care much and would go full private. i think the reason here is china. that way they don’t have to have a separate china policy which would draw undue attention to that point.


Reuters says it was because of the US as well: https://www.reuters.com/article/us-apple-fbi-icloud-exclusiv...


To the degree that's true, my guess is that, just like China, it's to manage public perception. That is, not "because of the US", ie some policy forced upon them.


If you ask around people feel like they have more privacy when using apple products, yet the truth is they all use iCloud backups, iCloud photos and iCloud drive, none of which are E2EE. Meanwhile, Google does allow for E2EE in cloud Android backups!

iMessage can be MITM’d by Apple when requested by the government and you, the user, will have no way of verifying your correspondent’s public key (unlike whatsapp, signal, keybase etc).


As you said it, but only if required by law.


>iMessage seems to be a bit dishonest, because Apple, the owner, has way more information about you through iCloud and Apple ID - contacts, location, payment data, phone number, etc.

But do they bring all that data together, correlate it, and sell it?


No advertising agency sells your data. That would destroy all their competitive advantage. They sell access to the people they have data on. Regardless, it's irrelevant because the App Store labels aren't about selling the data, but about what is collected. (or supposed to be, as claimed by Apple)


They don't sell data, they sell access to fine grained slices of their users.

"You want to advertise to 65 year old white people[1] in QAnon so you can pedal a very specific kind of fear? No problem."

"You want to buy access to black women under 30? We gotcha!"

That is what Facebook does which Apple doesn't.

[1] I know FB doesn't actually allow targeting based on race anymore. They do allow targeting based on interests though which can easily amount to the same thing.


They all pay to "share" data through data brokers in order to get more info about you. It's the same thing.


Facebook buys data from data brokers, but does not share data with data brokers.


Do you work for them? The way data brokers work, from what I understand, is that it's a 2 way agreement. You only get the data if you give data.


That's not how it works, they accept money.


Can any app on AppStore avoid declaring those flags if they say in their marketing that they don't sell it? Or why does it matter for Apple and not for them?


Data used to track you is gathered separately from data linked to you.


You can't know that. The moment it reaches their servers, you are not in control of what actually happens to it.


A government agency can still order them to hand over all data they have, they are still a single point of failure from a privacy point of view.


I think that's fair, but is certainly a different concern than what facebook is doing.


It is debatable what that data includes but even if true it isn’t what these labels are about. The list shows purposes and types of data and Facebook declares they use all that data for the purposes of tracking, advertising and analytics.


>iMessage seems to be a bit dishonest

Maybe I misinterpret the idea behind this list.

To me, its not listing all the things that the company knows about you, its listing all the information that app reads about you.

In other terms, this is what Apple knows when I disable the iCloud and only use iMessage. And this is what Facebook knows when I only use it though that messenger and nothing else.


That’s not it at all. If you have iMessage in your phone it’s completely tied to Apple whole data gathering context because your phone is made by Apple.

I understand what you’re saying. If the App is only collecting certain amount of information on its own, then they should only list that right? ... But that’s unfair with the rest of the vendors because they are forced to list everything they track, while iMessage obscures it by saying “the app doesn’t collect anything”...yet the phone is and iMessage is the default messaging system for iOS.

I’m a loyal Apple user but this is anti-competitive behavior. As much as I love Apple’s privacy focus, it seems that they’re using it as a proxy to unfairly compete with other companies and claim that they only care about the end’s user privacy, which is clearly not true.

Apple does and will use your data to push Apple products. They should be transparent about that.


> Apple does and will use your data to push Apple products. They should be transparent about that.

Explain how?


Anti-competitive for what?

Apple's News+ advertising empire? App Store advertising? Is there any evidence at all that they cross pollinate data in either of these contexts? If so, it certainly isn't clear based on the advertising I see in News+

Much of the stuff you are complaining about is "collected" because it's needed by other services. The real question is whether the data is reasonably siloed and how easy it is for Apple or third party's (governments, etc) to access and abuse.


Claims that company x oversteps privacy boundaries is often met with oh yeah? But Apple isn’t perfect. I agree, and I think there is room to push Apple to be a bigger advocate for privacy. Currently I think they are arguably doing the best job of this, however and pointing the finger at other people doing the same or similar behavior is not really an excuse. Pointing out hypocrisy doesn’t excuse bad behavior.


Those have nothing to do with iMessage though. If they aded them to the iMessage list people would naturally think that if they didn't use iMessage those things would be disabled, which is not true, so what you're asking for would be highly misleading and disingenuous.


That's the point, it's not about iMessage but it is about Apple. So to include Facebook things that are not necessarily Facebook Messenger things makes the comparison oranges-apples misleading


You're misunderstanding the warning on WhatsApp, those are the actual information specifically exposed by WhatsApp itself. The one for iMessage lists all the information specifically exposed by iMessage, so they are equivalent.


That may be true but I disabled that a long time ago and it’s _stayed_ turned off across multiple ios upgrades.

Unlike others os/phones where such things are turned on at every opportunity


Hmm, I'm being badgered to reenable iCloud on every single minor iOS update and rather commonly on macOS as well. Are you sure you were never asked about it?


I have iCloud turned on but it’s set to only sync Notes or something trivial like that that I don’t even use- I can’t recall ever having been badgered for more.

Maybe I got to that state because I was being badgered? It’s been long enough though I can’t recall.

Might be worth a shot if the risk is acceptable enough to you vs the badger.


I'll try it, but it was mostly for family members who didn't have any use for any of the cloud products.


The data listed for FB Messenger is taken directly from your phone and explicitly used for advertising and “other purposes”. If you added what Facebook has access to from your account it would cover two entire pages. Apples and.. blueberries?


It has its own section in the Privacy tab, which is exactly where I'd expect to find it. Hidden in plain sight maybe


It seems to be hidden enough that it's not added to this comparison.


I don't entirely agree with you here, but I do agree that Apple should be leading by example here and putting their privacy warnings exactly where they expect everyone else to. I want to be prompted for whether iMessage can be tied to data collected from other apps, or whether I should allow “Find my” to “continue accessing location in the background”.

For me, it would go a long way towards seeing Apple as not just trying to leverage their platform to be anti-competitive, but as a company who is honestly protecting my privacy.


I’m not an apologist or shill, but as a user I feel like I understand what I’m giving to Apple (or Microsoft/Google/$OS_VENDOR) when I am using their OS _AND_ enabling any kind of cloud sync. Maybe they’re taking more or less than I expected, but if I’m syncing my entire contact list I just have to assume now they have my contact list- and I accepted that when I enabled the functionality.

Some feature flags/settings across all the OSes get hidden, are non-obvious, on by default, or are flat out using dark patterns (looking at you Win10) but in general I assume the default state (for all OSes) is a combination of reducing support incidents, easiest on-boarding, and trying to push some corporate strategic objective summed up as keep the average user happy enough to stick around and possibly give us more money.

Any app I install on said OS, may want to access this information but without all the permissions explainers I have no idea what it’s going to want or why.

Again, I assume the OS has access to all of this because it’s the OS it either needs it or is the manager of the info and access broker.

To sum up my thought, I guess I agree that there’s a double standard but disagree that it’s necessarily bad or shady- but that’s because I already had a double standard in mind when I think about OS vs App.

Specific to ad-tracking and Apple: I have no proof for my belief but I believe Apple who primarily wants to sell me hardware and has made public acknowledgements of the importance of privacy, including making noticeable improvements to their OS, is significantly less likely to abuse my privacy than any other OS vendor out there.

I’m not saying this as a whataboutism, I just base it on my perceptions given all the things you just flat out can’t turn off in Win10 and that Google literally makes their money off of getting ads to your eyeballs and Android’s permissions are a dumpster fire nightmare for privacy.

I feel (again, no real proof) that the Apple eco-system is providing me the best _mainstream and low-effort_ steps to privacy protection vs the others, but I concede that it’s probably not good enough in many ways.


> iMessage seems to be a bit dishonest

i like to call it end to end to end encryption. i came up with that for zoom but it applies to iMessage as well.


I am not a fan of FB. Lord knows they are arseholes.

I _do_ like these labels, I think they are good.

but

It is dishonest to say the least that imessenger only has access to just those details. To use imessenger, you need an icloud account.

Tie that to the location services and any payment information, Apple knows everything about you, even more than FB.

The issue is about trust. rightly people don't trust FB with their data. However I don't think we should be letting apple off so lightly, especially when they are pointing the blame at other people.


To be pedantic you need an Apple ID rather than a iCloud account to use iMessenger. So in theory payment information isn't included.

However once you've got someones email or phone number you can ultimately tie it to any other data when you've used it elsewhere - medical records, phone calls to prostitutes, hacker news posts etc.

I think the difference is that Apple don't (or claim to not) use that data to categorise you and serve ads like Facebook. Apple make lots of money from hardware sales, a few cents from aggregating data is a drop in the ocean and they can take 'the moral highground' towards privacy.


I think the difference is that you are paying Apple to not abuse your privacy. With Facebook, you know you are trading some amount of privacy, but these new labels make it clear just what that true cost is.


I agree with this take, and it's the same take I share with friends and colleagues. It's certainly better than FB.

However, are we sure that Apple, in 30 years, will be the same proponent of privacy that they are today? Even if there's a 10% risk that they won't, they'll have your same data then that they have now.

Strong encryption with user-owned keys is the only way you can mitigate against this scenario. I'm optimistic that we'll get there eventually, but we aren't there yet.


The data they collect today will be worthless for advertising purposes in 30 days, much less 30 years.


Yeah, but the data can be used for many purposes other than advertising.


I am paying to trust apple with my data. Much more sensitive data than I share with Facebook.

I don't give facebook my health, location or payment details. Apple gets all of that and extracts a fee.

I don't give a shit about advertising, advertising is always about the aggregate.

What I care about is someone getting access to my data directly to do something with it. For me, my main fear is hackers and corrupt insiders.

Facebook is going to spend the next five years transforming from a naive company that is/was loosey goosey with peoples data, to I suspect a fee extracting privacy first AR platform. You might laugh, but look at microsoft, look how they have changed.


"you are paying Apple to not abuse" you

That sounds like a familiar business model.

Granted I pay for an email service that could similarly abuse me.

I think the goal should be to create services/software that make it impossible for a company to abuse people, so we don't have to rely on their word, or have to worry about them changing their word later.


Intent matters, simply collecting data to support the features you are providing is not inherently bad. Collecting data for third party ad targeting on ther other hand...

See: https://news.ycombinator.com/item?id=25684491


I don't think intent matters as much as you think, because the government millitary complex can force you to give that info in the first place and then use it for very bad purposes, like china and USA has repeatedly. Gathering such info while being aware of such realities and very wealthy is pretty bad too.


If only Apple didn't have a monopoly on the App Store on the iPhone. Then we wouldn't have to know this information because we could get it from a different App Store where Facebook doesn't have to share this info!


App distribution can be totally different from API access to my device. No matter where i get the app from, when accessing certain APIs i would get notified about that, or would have to explicitly enable that functionality in OS settings.


For Apple to know about API access the app would still have to submitted to them in some manner.


The idea was that the phone OS could detect the usage of those APIs and prompt the user wthout Apple having to be directly involved in the process.


"that the phone OS could detect the usage of those APIs"

This must be handled correctly as it can this also lead to privacy violation.


There is no reason it can't all be done on-device. That is indeed how the current "Enable camera access?" etc. system works.


This is not a question at all that this can be done or not ( There is no reason it can't all be done on-device. )

Question is will this be ethical .. I will not be comfortable using a device that logs every API an app on it is calling.


Why would anything have to be logged? Apple phones already do this and have done for years. With no phoning home.


Access control is not the same as logging - the first time an application tries to access the API the OS checks permissions, asks user to approve/deny, and then stores the user's choice. No need to log the actual API calls at all, no permanent records needs to be created.


Just like on device image recognition which Apple is already doing.


That's a pretty intentionally obtuse take on a completely unrelated problem


It is actually too obtuse, to be honest.

It would be better to be explicit: if it were not for the Apple 800 lb gorilla holding the Facebook 800 lb gorilla's feet to the fire here due to its self-appointed role as gatekeeper of the iOS App Store then this information would remain hidden from general consumers.


And while they force this to be disclosed about Facebook Apple hide its own data harvesting since they can collect via sources Facebook cannot. This is pure PR and abuse of market share to better Apple's own ad service.


You have repeatedly made this claim and have yet to provide even the thinnest shred of evidence. Please supply some or stop making these unfounded assertions.


I've seen multiple people allude to Apple secretly collecting data before. I would really like a source because it's very plausible but I haven't seen any independent research showing that this is actually happening or what's being collected.

Google searches turn up stuff like this: https://www.zdnet.com/article/apple-data-collection-stored-r...


If only Apple had a monopoly on all phones and computers so everyone would know it, right?


Why, the idea of an universal benevolent overlord is neither obscure nor new. It's basically the idea of God.

Do you know what's the problem with God?


What’s the problem with God?


Well, for one, God isn't Apple Inc..[citation needed]


I'd argue that if apple didn't have a monopoly, we'd have stores that catered to privacy conscious people far earlier.

If apple didn't restrict the OS so much, you'd have people making their own Facebook clients, wouldn't have mattered if Facebook liked it or not. The monopolization of Facebook's control on personal connections is partially because of closed OS's. And Apple's iOS is one of the most responsible OS's that gave rise to Facebook's data monopoly.

Had it been like Windows, there wouldn't be a way that Facebook could've maintained their monopoly.


There are other OS with a larger percentage of devices installed with other app stores possible. How many privacy focused stores do we see with privacy focused Facebook clients? How many of the users exercise those privacy options and give informed consent to share their data?

Hypotheticals can be argued either way but it’s just one possible option, not the only one.


The answer is chrome web store/firefox store and adblock/tracker block. They offer a hint into a more free future.

Imagine if adblock wasn't allowed on those stores. Today the equivalent is alternative clients to Facebook not being allowed on iOS and the App Store.

Look at YC startups like motion being built on top of the web. They are building on top of the network effects of gmail/google/facebook/slack etc. We aren't allowed any of that on mobile. Had they been allowed more access to the mobile OS's, they could be a very successful company. We haven't even touched the tip of cross OS productivity integrations.


> There are other OS with a larger percentage of devices installed with other app stores possible.

Like which ones? There's the AppStore, the PlayStore and that's it, nothing else is even worth being mentioned in terms of market share.


> If apple didn't restrict the OS so much, you'd have people making their own Facebook clients, wouldn't have mattered if Facebook liked it or not.

You're totally wrong on this. In fact, the first alternative FB clients I remember using sprang up on the iPad, before FB bothered to put a native app out for it.

What killed alternative FB clients was FB itself -- they've slowly closed off the APIs you'd need to access to make an alternative client optional. FB has also closed off their own alternative clients as well (FB Paper), and have been forcing users into their official web or native clients for a while.


I'm not sure that it really workout that way, you wouldn't have Facebook clients on these privacy conscious stores because FB wouldn't provide an open API which they could use. Otherwise are there any reasons why these client can't be published on the App Store besides that there no way to make one?

Instead it's probably more likely that FB would host Messenger and Whatsapp clients on their own app store with all the details hidden somewhere in the user agreement.


What’s the well-known privacy-conscious Android store that’s been running for a long time?



F-Droid proves your point.


Are there any "unofficial" Messenger apps on F-Droid?


F-Droid has a search box you could use to answer such questions for yourself:

https://search.f-droid.org/?q=facebook&lang=en


That was a rhetorical question. AFAIK the closest thing you can get is wrapper around messenger web app which (which by default doesn't work on mobile browser because FB wants to force everyone to use their native apps).


While it wraps their web app, I use Frost for Facebook, which is an open source app that lets me access Facebook messages on mobile without using any of Facebook's apps.


I thought that Facebook didn't allow for any unofficial clients, be it for Facebook itself or Facebook Messenger ?


How does using Facebook via another client prevent or diminish Facebooks data monopoly?


If you're serious about this question.

The the answer is: a competitor could build their services on top of Facebook. They wouldn't have to start from scratch. Independent client's mean if the one user trusts you with their data, you can provide them a bigger value.

Today you cannot innovate on top of Facebook. Their network effects mean if your service is superior, you need to beat the network effects first.

And Facebook cannot reasonably offer independent access because: Cambridge Analytica.

Independent client's do what they want without Facebook taking a hit on their reputation. No one blames apple for the crimes committed using their phones/computers do they?


I think that building a competitor on top of facebook is against their terms of service. You wouldn't be able to build an 'alternative facebook client', legally at least.


> I'd argue that if apple didn't have a monopoly, we'd have stores that catered to privacy conscious people far earlier.

That didn’t happen before the App Store and isn’t happening anywhere else after the App Store either.


We do one thing right! So we don't need competition because you can safely assume all other things are right and the way they should be!


Yeah Epic sure showed Google Play, didn’t they?


Is there a single time in tech history where a monopoly was not totally abused ? You are asking Apple to take over the world because you buy their privacy propaganda but ICloud is not even end2end encrypted, employee are listening to Siri conversation, Apple knows all apps you run and when instead of just providing a blacklist you compare against locally... There's a scandal every month about Apple privacy.

How long before they ban ProtonMail because "You know what, we think our emails are "better for you". How long before they ban Signal because "You know what, IMessage has a better security than signal so it's "better for you".

Monopoly / tech dictatorship are the easy and tempting solution but nothing good ever came out of giving some dude total power over you. And even if you like those dude because you buy their propaganda, many other people might not share your view.


Ironic — the article shows up obscured by a full-page overlay and a banner with my favorite phrase "We value your privacy" (I read this as "your data has value to us"), that goes on to say:

"We and our store and/or access information [...] and process personal data, such as unique identifiers and standard information sent by a device for personalised ads and content, ad and content measurement, and audience insights [...]

With your permission we and our partners may use precise geolocation data and identification through device scanning. You may click to consent to our and our partners’ processing as described above. Alternatively you may access more detailed information and change your preferences before consenting or to refuse consenting. Please note that some processing of your personal data may not require your consent, but you have a right to object to such processing."

I can then click "MORE OPTIONS" to enter the deceptive dialog, where you think everything is off, but really everything is hidden under "LEGITIMATE INTEREST" (another one of my favorite sneaky phrases). I don't know how you can really turn the tracking off.


> I don't know how you can really turn the tracking off.

Install a good ad blocker like uBlock Origin. You may also want to disable third-party cookies for good measure.


Unfortunately Apple doesn't allow such plugins on iPhone.

It comes full circle...


Doesn't iOS 14 have DNSoTLS? You could use that to block ads system-wide. I've been doing this on Android with my own sever for several years now, and it's so surprisingly effective that I forget internet ads are a thing.


Apple has allowed content blockers in safari on iOS for several years.


Which are much less powerful than uBlock Origin and only work in the browser (which isn't an issue on desktop, but on mobile a lot of the tracking is also done by apps, so blockers need to be more than just browser-focused).


I use the Lockdown Privacy[0] app, it saves me from most of the ads, although, not from the cookie popups. It works pretty great and is open source.

[0] https://apps.apple.com/us/app/lockdown-privacy/id1469783711


Beat the dead horse - news sites need money and show ads.


Showing ads is one thing, but more savage beasts lurk in the javascript jungle...


Ads are fine.

Have you tried clicking through those deceptive dialogs and have you seen the list of "trusted partners" that will receive and gather tracking data about you?

Do you at least know roughly what the number of those "trusted partners" is?

Take a look, it could be an eye-opener.


...and to continue to beat the dead horse, news sites can either (1) straight-up paywall their content or (2) show ads without invading your privacy.

Tracking in every form but the anonymous, opt-in, and truly optional (no restrictions (other than the obvious) if you decline) in not acceptable.


The article references a 9to5Mac article, which in turn references this article by Forbes, which I think should be the submission url instead.

https://www.forbes.com/sites/zakdoffman/2021/01/03/whatsapp-...


Already an active submission on it (https://news.ycombinator.com/item?id=25683727), maybe the threads could just get merged?


The Forbes article goes on and on and never really gets to the point. And it had to load for ~3 minutes for the cookie banner to set my preferences.


Well it's not entirely a fair comparison since iMessage doesn't support in-app services and purchasing like Facebook Marketplace, as WhatsApp does. For which naturally it has to gather additonal data.

Also until iMessage is available on other platforms, what it slurps or doesn't slurp is academic for most users of WhatsApp.


That doesn't follow, Apple provides 6 different purposes for collecting data linked to the user:

* Third-Party Advertising

* Developer’s Advertising or Marketing

* Analytics

* Product Personalization

* App Functionality

* Other Purposes

The features you mentioned would fall under "App Functionality" and as you imply it would be legitimate. The reservation with Facebook is all the data they collect for the five other purposes. In my own analysis of thousands apps[0] I explicitly excluded data collected for app functionality purposes because of this. FWIW most of Facebook's app collect 128 data types(by far the most of the ~5000 apps I've analysed) across those five purposes, WhatsApp collects only 18.

0: https://hugotunius.se/2021/01/03/an-analysis-of-privacy-on-t...


Why would I want in-app services and purchasing like Facebook Marketlplace in my chat messaging app? It should facilitate chat and messaging, and no more. This is how it used to be, until Facebook acquired and ruined WhatsApp.


Do one thing well is not the only valid model. For instance why would you want apps on your phone? It should facilitate phone calls and messaging.


I don’t think more features is the issue. It’s adding them at the cost of your personal data, especially when you need to pay the cost even when you don’t use those features.


It’s unclear that these data is collected if you don’t use these features.

Same as an app may need disclose it can use you mic, but it only does it if you use specific features. (The model for such permissions used to be before installation on Android and improved over time, and perhaps something similar can be done for data collection permissions as well)

Right now, more features, whether you use them or not, will have their data collection appear on this screen, without context. So while these labels are a welcome addition, they can also be scarier than reality.


Because other chat systems in other countries (like WeChat) did, it was a great success and FB copied it.


I don't know about that, I have literally never used it or heard of it. It was today I learned that WhatsApp has a bunch of these useless features.

Besides, China should not be your model if you care about privacy.


You're saying that WhatsApp needs more data for additional features. But I don't use Facebook Marketplace, I just use messaging; it makes sense for me to compare WhatsApp with apps that act as communication tools only.

I think most WhatsApp users see WhatsApp like this and I'd guess article's authors assumed the same.


Maybe FB should have let WhatsApp be a messenger then and made the Marketplace its own app. But this way, the tracking functions can be pushed to everyone under the guise of the Marketplace functions, even if they only use the Messenger.


Facebook is persona non grata when it comes to trusting them to use information that they’d obviously need for a service only in the way they’d obviously need to use it while not adding it their advertising database.


We should understand Facabook was the best platform to advertise mobile game apps and etc, for almost 10 years. Apple took 30% of all that revenue without any objection.

Now Apple has its own ad infrastructure, and this is a perfect strategic move by Apple.


This is cute and all but so long as Android (and to a lesser extent Windows/Linux PCs) cannot run iMessage... what does any of this matter? Yeah iMessage is great between me and anyone I talk to with an iPhone, but it's still largely an Android world and in the best case scenario I can convince an Android user to install Signal, but usually not.


Well, that's the point from Apple's standpoint, right? It's marketing for them to convince you to convince your friends to buy iPhones. And in the mean time they'll keep blocking out apps like Signal from integrating in iOS the way they can in Android.


To be clear I wasn't trying to defend Apple here, it's more in the spirit of meaning they should just shut up about how great they think iMessage is so long as it's only available on Apple devices.


Like many other unpleasant facts it is one thing to know something is happening and another to have it proven to your face in an indisputable format.

However I have to ask, will this become another surgeon generals warning or calorie labeling of restaurant menu experience? By that I simply mean, people will not only click through it but also accept it as they don't see any real cost.

Eventually as with everything presented under dire warnings you drown your audience to the point they tune it all out and go right back their blissfully attitude of just accepting it under the guise of its not going to matter


YMMV, but I actually do look at the calories before ordering at a restaurant. There are times when I have ordered something else because of the number of calories was too high in what I wanted.


If it’s impossible/forbidden/very costly for the vendor to put poison in the food, then they won’t do it. Nobody will come and say „I would like to have this extra fatty extreme glucose meal, please“.

This is why we need opt-in instead of opt-out as default.


I'd love to be able to see a table/grid listing my installed applications along with the permissions they've been granted.

I read through WhatsApp’s new terms and I don’t understand what the big deal is. Isn’t it mostly about messages with businesses?


The changes differ based on your location.

In the EU (and UK), it's some fairly minor changes to do with business messaging.

Outside of the EU, it is much more significant, merging your WhatsApp data with your Facebook data (including the phantom profiles FB create for users who don't have accounts). They can't do this in the EU (yet) due to privacy laws.



I am flabbergasted that this author attributed to 9to5 mac the privacy labels of different apps in the screenshot, when tracing the sources shows it was Zak Doffman at Forbes who created it. Poor journalism.


Expect more of this pushing competitors out as Apple transitions further into the 'services' business model by monetizing their vast trove of user data.

MSFT and GOOG have been doing this too for years ofcourse.

While GOOG has had to be content only with what they can read from emails/calendars, texts, web searches, calls/voicemail, maps/location data and anything else that they can scrape from an Android device.

MSFT has had all of that a much, much more since they own the whole OS for workstation/server class devices where actual work gets done. MSFT will claim that all that data is for quality control and now security services but ofcourse they are going to squeeze every last drop of money they can from it. To expect otherwise would be like asking an alcoholic to guard a brewery and never sample the product, completely ridiculous. The US has no serious legal repercussions for doing so. Probably because the US intelligence community depends on that data since IT is forbidden from collecting it from Americans on its own.

Gee, I wonder why...



What search history is linked to iMessage? Is it the searches you do on your phone?


Problem is that most people already have WhatsApp installed and won’t be looking at that label anytime soon. Even if they had to reinstall it, they would likely never look past the download button


Gee, talk about a massive "pot to kettle" story.


Funny how this article bombarded me with cookie popups


Well of course they hunger for user data. THey are free services. Would you rather have to pay for whatsapp? Or have banner ads? Because I rather not

And the comparison to imessage is a bloody joke. You already paid a shitton of money for your iphone, they don't need your data for anything


> Or have banner ads?

You do realize that this type data collection is almost always in service of displaying ads, in some way, to users, don’t you? There’s been reports about FB working to add ads to WhatsApp for a while now [0].

[0] https://www.techradar.com/news/whatsapp-could-be-getting-ads...


I remember when you had to pay a buck a year or so for Whatsapp. I really liked the feeling of this straight forward business model and paid.


Good luck justifying the 19 billion dollar they sold their business for using $1/user/year.


How sustainable is that $1/yr tho I wonder


Would I rather have to pay?

Fucking yes! This should be the default. The default should be pay, with a free option that requires you to dump truck all your data.

Tech giants have completely ruined the internet economy. You can’t even pay for these things now. It’s just hand over all your data and secrets, or fuck off.

And the worst is that new businesses can’t compete unless they do the same. You can’t compete with free.


IMO it would be perfectly reasonable for everyone to have an Internet connection(s), and much of the rest is handled by community efforts. That's how Bittorrent works, and it's very scalable and open. Emerging protocols can add privacy. Solid is another effort in this direction, where any third party could host your data. Finding ways back to that (since it's more or less how things worked pre tech giants) offers a lot of solutions. The tech giants could even pivot (or be forced to pivot) to this approach, which is simply about being less captive on particular ecosystems. It's not even the grand vision of rich interoperability that doesn't depend on backroom deals, which is what we should be talking about now.


imo, that's a very, very dangerous proposal. I agreed with you for a couple of seconds, but this sounds like yet another way to fuck poor people.

It should just be default to not collect unnecessary data, whatever that may be, while being free. Maybe make paid plans with premium features. Everything else will just mean that Big Tech can spy and manipulate poor people, because they can't afford to pay for every service they (have) to use. We should stop tying privilege to money.

Maybe I'm being too dramatical, but that's what came to my mind after reading your suggestion.


Access to internet services is not some fundamental human right. No one HAS to use these services. You can live a perfectly fine life without FB, WhatsApp, Instagram, Twitter, Google, etc. I don’t have accounts with any of these services. My life is better for it.

Moreover, paying for goods and services is how the economy works. Netflix does not have a free tier. Are they fucking over poor people?


1) It is not a fundamental right at this moment, but I think it should be in the following decades. More and more things are expected to work online, with offline alternatives existing. And you are mixing general internet access with individual platforms. Sure, nobody has to use Twitter. There are situations where one is forced to use one of these platforms. And I know where you are coming from, the only account I have is from Google.

2) It's not wrong, not to have a free tier. It's not wrong to have paid plans. What I think is wrong, is defining that surveillance should be the default. Give me the option to disable analytics etc. completely. Tying this mechanic to money is wrong. You shouldn't have to pay to not be spied on.


That is wildly inaccurate. Apple should report for each of their apps the iOS data they are collecting on top of the application specific data. Apple has my location, my friend's location, my contact list, and stores all of my iMessages with the encryption key in iCloud.


As far as we know (and evidence seems to support it, apple does does not hand out users data to authorities) apple cannot decrypt your data at will.


At the phone. At icloud is a different story.

"Messages in iCloud also uses end-to-end encryption. If you have iCloud Backup turned on, your backup includes a copy of the key protecting your Messages. This ensures you can recover your Messages if you lose access to iCloud Keychain and your trusted devices. When you turn off iCloud Backup, a new key is generated on your device to protect future messages and isn't stored by Apple"

https://support.apple.com/en-us/HT202303


I think this is the best way to do it.

- If you want to hold the keys to your backups and set up the system to be private, you have the option to do so, and are presented with that option at the time the device is set up (and you are also presented with the option to use a local backup to restore or set up a device). The implications of the choice to use a cloud backup should be made more clear, though.

- For the vast, vast majority of users who don't have good backup hygiene, having someone else manage backups and hold decryption keys is a good trade-off, considering that the alternative is total data loss.


e2e encryption for all icloud data + a dialog prompt on whether you authorize to store the decryption key on the server would suffice.


I see this diagram posted everywhere on the internet, and whilst of course Facebook collects a lot of data, in this situation I believe they just selected every option available to them for display on their app listing. If they declare every single option that Apple presents then Apple cannot complain, and it is not going to deter end users one iota from downloading the Facebook app and the other Facebook owned properties.


Kind of stupid to compare against Imessage. It says Imessage can link to your device id. And once apple knows the device id, they basically know everything about you since they own the device (remember: you don't own your Iphone). It is admirable that signal is not using any identifiable data, though.


> It is admirable that signal is not using any identifiable data

They don't need to. You identify yourself within the app with your login.

> It says Imessage can link to your device id

While iMessage is vulnerable to (certain) MiTM attacks, and storing your message archive in iCloud is (was ?) unencrypted, iMessage is surprisingly resilient to attacks (on the protocol itself).

Every iOS/Mac device generates it's own key and uploads the public certificate to Apple's keyserver, this is why they need your device id.

When you send messages with iMessage, your device then contacts Apple's keyservers, gets ALL public certificates for the recipient, and encrypts the message once for every key, and sends an encrypted message per device.

Attachments are handled a bit different. Insted of encrypting the attachment n times, a new key is generated, which is then used to encrypt the attachement, the encrypted attachment is uploaded to Apple, and the key is sent using normal iMessage messages (encrypted)

Your private keys NEVER leave your device, so iMessage is end to end encrypted as long as you don't enable iMessage in iCloud.

I said that iMessage was vulnerable to MiTM attacks, which it is. There's nothing stopping Apple from adding a "shadow" device to your list of devices with it's own set of keys, which would then receive a copy of every message sent to you, and that's probably how iMessage in iCloud works, but they have no way of retrieving your message history from before the shadow device was added.

There's a somewhat recent (2016) paper on it here : http://www.cs.tufts.edu/comp/116/archive/fall2016/xshi.pdf


> They don't need to. You identify yourself within the app with your login.

By that logic even whatsapp/facebook don't need anything apart from login. So why do they collect all the other stuff? Signal is making an effort to make do with the minimum amount of data.

> While iMessage is vulnerable to (certain) MiTM attacks

Apple doesn't need to MITM Imessage. They own the app, service, and devices on both sides. That's why it's silly to compare it with whatsapp/facebook.


iMessage in iCloud is end-to-end. Probably you are confusing it with the iCloud Backup, which is not. iCloud Backup contains the Messages in iCloud keys anyway, so if you want the best security it's better to not use iCloud Backup.

https://support.apple.com/en-us/HT202303


Seems i was wrong, though backup is encrypted. The "issue" is that the encrypted backup contains a copy of your key used to decrypt the (encrypted) messages within the backup.

https://support.apple.com/en-us/HT202303


Yes, but you can use Messages in iCloud and keep iCloud Backup off.


Phone number can tell more than enough (as phone is used as a user id in Signal).


And at the same time Apple pretends not to do this themselves since they can harvest the data in other ways so iMessage doesn't have to show as many warnings. Very disingenuous and pure PR (that clearly is working as intended even on HN). With cloud, iMessage and a unique advertising id Apple knows way more about its users than Facebook does. Great that Facebook gets exposed, but naïve that people believe Apple collect less.
