The closest to what Twitter used to be is Bsky. The model isn't perfect and some of its features are still not quite there, but it has replaced my Twitter usage entirely. And they've managed the large user surge pretty well. I've seen some developers I follow who cross post getting more engagement on Bsky than X despite a lower follower count there.

Most of the people you mentioned wouldn't risk their money for something like moral values so they haven't left X. A large number of interesting, less self motivated people have migrated already.
