My organisation has a requirement that we build to work without JS. If we need to use JS for something then we also need a non-JS alternative, the result may be less pretty/fast/require an extra call but it works regardless of your JS choices

but that's the problem: the ads and trackers don't work!

unless you're willing to pay them with your data and eyes, they won't let you see the site.

not that I agree with this.

>As a side effect, most of ads and trackers also stop working.

As well as a lot of sites, period.
