I'm deeply skeptical about all the noises blueSky has made about "federating." Let's define what that would mean so we are on the same page: people in the fediverse could follow blueSky accounts AND blueSky users would be free to follow anyone on the fediverse rather than being in a censored space.
We already have the first one. But without both? It's not really federation.
BlueSky has said they will do this, only pressure from their users can force it to happen.
