From what I have seen using Bluesky this isn't true at all. It's brutally censored, even more than Twitter was in 2021. Or are there other relays and appviews I can use that aren't? Is there a comprehensive list of Bluesky infrastructure that isn't run by Bluesky themselves (excluding a PDS)? Or is it totally centralized for now?
Wow, "brutally censored"? This is the first I've heard. What are you referring to? (I don't use Bluesky).
Check what the default moderation service is flagging. I understand that the standard Bluesky site moderates however they want, and that's fine, but this is a decentralized network right? So a productive discussion is to discuss what other relays and appviews are currently running where the users can pick and choose that algorithm, as content exclusion is perhaps the single most important part of any content algorithm, and the defaults on standard Bluesky are pretty locked down.
