Dorsey left Bluesky precisely because the other people there felt they had to implement the old-Twitter-like checks and balances that caused him to leave Twitter in the first place. As such, it's completely out of his influence.
Yes, it's still one monolith waiting to be gobbled up by someone with a lot of cash, or to spiral down into what would seem to be almost inevitable enshittification, but it hasn't done either of those yet, and both the good and bad there mean it's the closest there is to old Twitter at the moment.
Please note that I'm not saying that everyone should go jump on there and use it, or even that we have to like it. Just pointing out that Dorsey has nothing to do with it any more.
Speaking of Dorsey, he went back to endorsing Twitter for a while, but now he's started Edit: endorsing yet another platform called Nostr. Probably the better candidate for being avoided right now.
I have no such "but actually" about Threads. Definitely worth avoiding, even if it is supposed to be able to Federate.
