Technically on Bluesky even if you don't own your own domain you can still move all your stuff to a competitor and everything will still work. The only thing you can't do is keep your original handle but no "links" to your account (posts, followers, comments) will be broken because there's a stable identifier for your account that's independent of your handle. You will still be verifiably the same person on the other server.
