You could spin one up this evening if you wanted. Or go use catodon.social.
That's not the point. The point is, there are reasons Mastodon is being rejected, just like there are reasons you seemingly cannot pay people to use a Misskey-based or Hubzilla-based website.
It's not where the people are going, and the public or semi-public figures are going to follow the people.
In a word, audience. I'd prefer it if everyone went with Mastodon, but the audience on BlueSky is orders of magnitude bigger. I cross post to both, but only because I don't trust BlueSky not to do exactly what Twitter and Meta have done eventually.
I think there's a fairly serious problem for large accounts on mastodon but I will never have one so I can't quite understand it myself.
Something like dealing with replies / scolds without spending all day blocking is too hard.
It doesn't help that "no algorithm" means "show first reply at the top" so quick replies can dominate comments.
The bit I don't understand is why this is fine on blue sky. Is it just different users? I can't quite believe that but I can't see why blue sky would be less annoying.
