The difference is diversity of opinions. There is none on Bluesky. Anybody can voice their opinion on Twitter/X. On Bluesky you'll be quickly shun by the entire community or straight out banned for not agreeing with specific partisan talking points, no need to list them, it's similar to reddit editorial policies. If you deem Twitter an extremist social media, then Bluesky is even worse,as it just only allows one sort of extremism, one kind of ideology.
