>and would instead favor people self-curating mechanisms like RSS readers etc.

That isn't what would happen.

What would happen is that only the platforms which can afford legal teams - in other words, the big platforms - would host user posted content under strict arbitration only terms, and every other platform (including Hacker News, which uses an algorithmic feed) would simply not. Removing one of the cornerstones of free speech on the web in favor of regulation will only centralize the web more.

And you wouldn't see mass adoption of "self curating mechanisms" because most people aren't like Hacker News people and would find the premise of having to manually curate data feeds from every they visit to be a tedious waste of their time.

I also think that platforms like Youtube and Tiktok shouldn't be illegal. I don't even think that personalized algorithms should be illegal - it's surprising that one has to point this out on a forum of programmers - but algorithms have no inherent moral dimension and the ability to use an algorithm to find and classify relevant content can be useful. The same algorithm that surfaces extremist content surfaces non-extremist content. The algorithm isn't the problem, rather the content and the policies of these platforms are the problem. And I don't think the solution to either is de facto making math illegal and free speech more difficult.
