"#Bluesky and #ATProto are not meaningfully decentralized, and are not federated either.
However, this is not to say that Bluesky is not achieving something useful; while Bluesky is not building what is presently a decentralized Twitter…
…it is building an excellent replacement for Twitter, and Bluesky's main deliverable goal is something else instead: a Twitter replacement, with the possibility of "credible exit"."
