I completely agree with everything you've said. My main point is that I suspect this is a natural development even with all economic incentives and Algorithms set aside. Facebook et. al. are capitalizing on social psychology that would be there even if they weren't. You can see the same sort of echo chambers taking shape in other fora such as 4chan, Reddit and Mastodon. These do not incorporate the Algorithms that are often solely blamed for the outrage cycle.

Regardless of actions taken against (or complete elimination of) the big commercial players.
