Bluesky seems to be pre-Musk Twitter 2.0. Its content is basically the same (art + "look at the bad thing the Republicans are doing - the Democrats will solve this"). Its moderation policies are basically the same (post anything too different from what's there = ban. Centralised moderation). Its user base, although smaller, draws from roughly the same pool. And Jack Dorsey made it. And it even has a blue logo. It's clear he just wanted to create Twitter a second time and succeeded at that.
