Yet another shitshow-in-waiting. I know Mastodon isn’t as polished but leaving one frying pan to get into another is a lost opportunity. I failed to convince somebody to move to Mastodon recently.
Bluesky I got in before it was opened up by adding my email to the waitlist. Simple. And now it's even easier because there is no waitlist.
I used it and found a decent one, managed by someone relatively local and active. Most of my followed accounts are on other servers but I haven't seen that as a big issue.
