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?

I think that is a very bad analogy, because all of those are browsers that (historically) had all their different underlying engine but basically everything made the same. It was the same functionality implement 3 times.

With AP, AT and whatever X uses, it's a completely different mechanism.

So it's more like an Single Player Game, and Online Shooter and an MMO. In the end everything is a game but the way they are built and functioning is completely different.

Huh?

3 browsers that at the time of the browser wars had three different rendering engines?

3 social networks that at the time of the microblog wars run on three different protocols.

Maybe it's a thing about analogies that they don't need to be 100% accurate. So I guess it's ok 😄
