How does ActivityPub differ from what BlueSky is using? (AT) (lemmy.ca)

I don't quite understand a lot of the details on how the implementations work.

In what ways is AT better or worse than ActivityPub? Are there different versions of ActivityPub? Are there improvements coming to either to make them better (or compatible)?

My current understanding is

  • AT makes it easier to move accounts (according to them), but AT is controlled and maintained by BlueSky, and they are a for-profit company that can mess with the protocol in the future, which goes against the central idea of decentralized social media

What other cool technical details are there?
