"Censored" I mean "flagged", sure. In practice, they're all hidden from the casual user. But really, I'm interested on why ATProto was touted as revolutionary while in practice it powers a standalone heavily politically biased social network where moderators are extremely active flagging everything that's on the right. In that respect, Mastodon is more "revolutionary" - you handle your instance, you provide your moderation, you optionally integrate with other instances. Mastodon itself is used, in practice, to moderate a highly diverse ecosystem of social networks, from the gay-friendly ones to Gab. Nostr, although it's not so widely used, is even more tailored against sectarism by default.

From what I see, Bsky is a single instance of one of the most politically aligned social media in existence; in practice, you can achieve that with any proprietary implementation, you don't need ATProto. I honestly thought that the protocol was engineered to prevent an echo chamber, but in reality it powers an enormous standalone echo chamber that is not moving anywhere, so I was wondering what's the difference.
