Your best bet is to be in a lot of instances. My experiences so far is that basically any singular instance has its bias’, and while some unapologetically ban users for disagreeing with them, the ones that don’t still down vote for disagreeing with them.
While one of these forms of censorship is worse than the other, it’s all censorship, and the only way to see a variety of views is to stay in the varying instances.
I’ve also heard some “running it offline avoids all the Chinese biasing and spying” anecdotes. Though I haven’t seen any first hand evidence of this. Needs testing, imo.
