also, bluesky is doing well because essentially, most people going there don't care about its decentralization premise
in the contrary, they're nostalgic for the old centralized twitter app, and bluesky provides this experience (including the logo)

despite the efforts and promises of some of the founders and developers, it's not really a step forward, but for user adoption success it doesn't need to be

when bluesky has its own "Musk event" those users will just hop to the next centralized platform again, none the wiser
