I should have been more clear. The neat thing about the entire CC class of licenses is that it's easy to pick from what you want to do based on what you're doing. A license framework if you will.

The GPL doesn't have that - and as you said, CC-BY-SA is probably the closest - but I don't have to use CC-BY-SA if I don't want to. Maybe I don't care as long as my name's on it. Then I can just use CC-BY.

The FUD you speak of is another reason I tend to shy away from GPL - both in terms of enforcement (shown to be tricky, thought the SA CC license would have the same issue), and it's association with RMS and the culture and FUD surrounding it.

Another thing is that CC lends itself better to things that aren't computer code.

GPL is like donating a loaf of bread, but saying you can't make a ham sandwich with it (because you just hate them pigs).

You either want gift the code to the world or you want to do it conditionally. Do tell me which one comes across as a more genuine gesture.

Ah, the inevitable "bad GPL analogies" portion of any GPL discussion thread.

I personally don't feel I'm under any ethical obligation to give away my source code. Sometimes I don't release it at all, at least not unless you're paying for it. Other times I license it under a permissive license, usually when it's something smallish.

And other times I choose to GPL or AGPL it. I see the latter case as a quid pro quo: you can use my code as long as you let me use yours. Unlike in the ham sandwich example, it's not some arbitrary restriction imposed out of taste or spite, but a proposal of what seems to me to be a fair exchange. In return for using my code, you let me use your code, pretty simple and symmetric.

If you don't like the idea of a reciprocal code exchange, we could agree on a different exchange, like you paying me money for a license, or we could fail to reach an agreement and no exchange happens. But I don't feel particularly obligated to give you unrestricted free use of my code with no reciprocation. I could choose to do that out of charity or idealism, but I don't think I'm obligated to.

The trouble is that even in that simple post, where I think your real point is perfectly reasonable, you have completely mischaracterised the GPL and AGPL.

The GPL doesn't actually say "you can use my code as long as you let me use yours", or anything very similar really. I expect you knew that and didn't mean any deception by what you wrote, but we're talking about a legal document and lawyers are not known for their folksy interpretation and sense of humour.

And the AGPL is a particularly dangerous document that shouldn't be directly associated with any of the other GPL-related licences IMHO. Its scope is broader, because it can have profound implications for anyone even using software distributed under that licence, not just those developing the software.

True, they're not specifically licensing me to use their code in exchange, but I still think conceptually it's within my rights to offer that sort of exchange. I make a blanket offer to let you use my code, if in return you offer your own code under the same blanket offer. It's even more limited than that in that I'm not demanding you offer all your code that way, only the stuff that directly derives from and/or links with mine.

I don't see what's particularly dangerous about the AGPL, though. It's not that hard to comply with: if you build a webapp on some AGPL'd software, you need to AGPL the whole webapp. If you don't want to AGPL the whole webapp, you can just not build it on top of AGPL'd software. Pretty easy to avoid! And in any case the usual alternative to the AGPL is not releasing code at all, or releasing it under a "no commercial use" clause, which certainly doesn't give you more freedom. Compare Gitorious's code (AGPL) to GitHub's code (not released) for example. In both cases they're worried that if they MIT/BSD'd or even GPL'd their code, a rival SaaS could leapfrog them starting from their own code.

[edited the 2nd paragraph above for brevity]

The example that really got to me with the AGPL was when the Opa programming language was being discussed on sites like HN a while back. IIRC, both the language and its standard library/runtime were AGPL'd. That would potentially mean that not just the compiler itself but any program you wrote in the language would automatically be AGPL'd as well.

As with all of these GPL-style licences, there's a lot more risk if you're not an all-GPL house, and quite modest risk if you're intending to GPL your code anyway. But the AGPL is different because it can affect not just developers building on the code for redistribution but also those who are just using it internally.

I can understand why they did that, in the context of network-enabled services, but nothing in the AGPL seems to restrict the implications to only that context. As the example above demonstrates, people do use it for other things with potentially profound implications that aren't obvious to anyone who knows about the much more common GPL and LGPL but doesn't realise why AGPL is fundamentally different. For that reason alone, I don't think the AGPL should have used a similar name.

I agree on the name, yeah, and I was also surprised by Opa. My assumption in infrastructure-code cases like that (not sure if actually true with Opa) is that they want to leave the door open to a dual-licensing solution, so if Opa ends up being a killer technology, the AGPL poison-pills it enough for commercial customers that they'll be able to sell paid licenses.

Not sure what a cleaner alternative would be in that case. Perhaps just state that explicitly? "You can use the free version of Opa to build open-source webapps [define appropriately], but need a commercial license if your app is not open-source."

What is "bad" exactly about this analogy? GPL is a strongly conditional permissive licensing that carries an agenda. Compared to an unconditional license, it clearly has a lesser appeal to those not caring or not aligned with an agenda.

That's a poor GPL analogy. I think most of us know what the GPL says, and it does not restrict what you as a developer can make with the code (or regenerating bread in your analogy).

You can make all the regenerating ham sandwiches you want from the regenerating loaf of bread. The GPL only restricts what rights you have to pass along to anyone you give ham sandwiches to, basically ensuring that you do not have a monopoly on regenerating ham sandwiches.

You might consider that restriction to be just as onerous as restrictions on what you can make with the bread, but I think there is a categorical difference. The GPL only affects transactions with other people. You can use the loaf of bread for making ham sandwiches or biological weapons and the GPL has nothing to say about that.

Not only can you make the ham sandwich, but when you give ME the ham sandwich I can put mustard on it, and when I give it to some one else THEY can put cheese on it.

Because that's what the GPL does . It ensures that the right to modify the (sandwich)program never gets taken away from the next user in the chain.

>You either want gift the code to the world or you want to do it conditionally. Do tell me which one comes across as a more genuine gesture.

Making a moral judgement as to the license I release my creations under? This kind of idiocy is why I don't want anything I do to be associated with Stallman and his ilk.

"What's that? I'm evil because I sell software and don't give away the source code? Go fuck yourself."

And yet I've no doubt you'd be happy to call somebody who knowingly sold you a car you could not service "evil" (or something to that effect). Or what about companies that sell you content with DRM, preventing you from even doing legal things with it?

Now, perhaps you are fine with both of these things. And that's not an entirely unreasonable position to have. But not being fine with DRM or unmodifiable products is also fine, and disliking companies that sell these is completely valid. Disliking proprietary software is just taking the same idea and extending it, which is also entirely reasonable.

>Id yet I've no doubt you'd be happy to call somebody who knowingly sold you a car you could not service "evil" (or something to that effect).

Actually, I'd not buy such a car in the first place. But you're really not resorting to car analogies right?

>Or what about companies that sell you content with DRM, preventing you from even doing legal things with it?

Same thing - I don't buy it for the most part.

However, being anti DRM and being a FOSS zealot are two different things.

You'd be surprised how much "unmodifiable" software indeed ends up modifiable when enough people get interested.

In any case, I take great offense at the notion that I am somehow a bad person for not letting everybody in the world use my product for free, hence the notion at the end of my previous post. Which still stands, downvotes be damned.

It's more like donating a loaf of bread but stipulating that the person you donated to cannot sell it for profit.

So really, using the GPL is like donating to a non-profit where using a BST/MIT license is like donating willy nilly to any person or corporation regardless of their aims or practices.

But really, the whole analogy is deeply flawed.
