@Tim Bray what do you think??
BTW, most people think they don't need to understand whether or Bluesky is decentralized, a claim they make. Here's why you should care. If Bluesky gets a govt order to shut down your account, they can. That's it. That's how you know it's centralized and why you should care.
Before declaring democracy over, as our major news orgs and tech companies seem to have, remember there are still 50 states, most of whom still seem to accept that votes must be counted, and the winner is who gets most votes, not the one who sends in a mob to trash the state Capitol.
Imagine a client app that connected to mastodon.social and Bluesky. You could read threads that include posts from both systems. Voila, if a billionaire buys Bluesky, switch to masto. Wouldn’t cost say $30 million and could be done pretty quickly. 😁
