And this bumps up against another part of Cory’s enshittifcation concept: it only works when switching costs are high. Social media can make that work.

But, on the whole, the communities are built around topics, and it’s kind of easy to just move elsewhere (again, fediverse options Lemmy and Kbin are already looking pretty nice for that).
