That's why bsky's pseudo-federation isn't as big a deal as some ActivityPub boosters claim.

As I understand it, if lemmy.world shuts down or starts demanding cash my only resource would be the same as if Facebook decides I'm too critical of billionaires -- start all over elsewhere with a new account. Sure, I could get close to the same experience with a different node, but I'd be a brand new account with no history. I might as well go someplace else entirely.

Bsky's "portable user" idea fixes that. There are accounts my bsky account follows who switched to blacksky, and if they hadn't said they'd changed I wouldn't have noticed. The essential identity of their account shifted almost seamlessly, and they "federate" with everyone else, aside that their appview shows accounts that bsky's ordinary moderation hides.

I don't have any illusions about how altruistic the cryptobro VC's are. But the entirely of their value proposition is that "leaving bsky" should be about as painless as porting your number from Verizon to AT&T.

I'm easily out if they screw it up, I'm in the fediverse at least as much as there. So far, I'm OK with them and I want to see what happens with this protocol. Mastodon needs some work too.
