Bluesky has other problems besides centralization. The reason Bluesky is so centralized is that it's *really* expensive to run an alt Bluesky server that provides a home for users who have left the main server (a "relay" in Bluesky-ese). Partly this is down to tooling: because no one has done it, Free Our Feeds will have to invent a lot of stuff to get that server up and running, but people who come later will benefit from whatever Free Our Feeds develops along the way.
