Bluesky is just as centralized as Twitter. If you really want a decentralized Twitter clone, check on Mastodon. See my post today for a few brief words about it. I'll try to follow you as soon as I can figure out the strange Bluesky/Mastodon link (mentioned in my post).
I don't think anyone that is going to BlueSky these days cares about decentralization. I think that was one of the greatest marketing blunders $HIVE did, was focus it's message on being decentralized. I think people wanna go where their friends are. Which is BlueSky right now, until it's not cool anymore LOLOL
