For me, the most meaningful test of decentralization is whether one player can decide what most of the users can see. And that is entirely the case with Bluesky.

If the single centralized app gets sour, you will be left with the impossible task of coordinating all your contacts to move elsewhere. If the single centralized app is down, nobody sees anything. How is this progress?
