Sorry, I don't follow. Are you saying that he should leave a social network website because some of its users are bad? Or that the people that run the website are bad?
And also, there's some alternate microblogging site that is less hostile to truth and civility? Which site is that?
Lots of the users are bad, but the owner specifically tweaks and changes the algorithm to suit his own agenda and push his stance. That's what makes it an unserious platform.

Mastodon, by definition. Any hostile instance can be left for a better one.
