I know to some extent I'm shouting into the void here, but with cohost on the outs I would really encourage people to at least have another look at Mastodon.
It's the closest another social media has to being personally curated like cohost, and yes, I'm not actually the biggest fan, but it's the only one of the current generation of social media sites which isn't compromised from the start by corporate foundations/meddling.
Mastodon has a lot of flaws, of course (ask me about my attempts at contributing to it back in 2017), but I am not comfortable with using Threads or Bluesky given who runs them and tbqh I don't think anyone should be. Take the lessons you've learned from cohost and apply them to Mastodon and I do believe you'll have a better time there.
