Ideological zealots are more or less the only people who hate the modern web so much that they want to quarantine themselves within an entirely different and functionally limited protocol or ecosystem. Everyone else is fine discussing camping in Facebook groups and on Reddit and wherever, maybe just using an ad blocker.
I don't think there's anything terribly modern about a collection of large companies trying to present themselves as the entirety of a given thing (the internet in this case).
I don't think any social media platform has ever actually tried to present themselves as the entirety of the internet.
I don't think anyone actually believes social media platforms comprise the entirety of the internet, either.
But isn't really what people tend to complain about when they complain about the "modern" web. Mostly it's the complexity of websites and the presence of advertising and javascript, the homogeneity of frameworks versus the "quirkiness" of hand-coded HTML, the consolidation of content into platforms (versus, again, hand-coded HTML) and the fact that the web no longer entirely consists of people like themselves. And now AI, of course.
And the fact that every single alt-web is more restrictive than the web, almost universally antithetical to "design" or "creativity" as opposed to pure hypertext, and seems meant to appeal only to the strictly technical mind, bears that out.
