That turns web into 1990s style BBS.
Very cool for about two days.

I do not give a fuck about design if it is meant to exploit.
Sorry if your website depends on heavy use of JS third party integrations. I won't use that shit.
It's mainly functionality not design.
That's just how modern web works. Client side rendering and such.
I think turning off JavaScript is like a pilgrimage. It's meant to make you suffer to make you conscious about some things.
The truth is, most tracking does not rely on JavaScript and often not even on cookies. You are better off with a good ad blocker and JavaScript on, because the adblocker blocks known third party trackers which can be as simple as loading an image.
I use Matomo for analytics, it is privacy preserving for users (I don't want to look at IP addresses and things like that, only at trends), but all it needs is access log. You don't even see it.
But if it's religious (privacy) pilgrimage you are after, it's good. For real effects, you need a different practice.
Pure CSS is sometimes beautiful magic.
