Sure Meta will probably extend AP for their own use but it’s not that they can simply decide that the new feature that they introduced and is at first only working on their platform is the standard from now.
Maybe not formally, but it might not matter. Looking at how google implemented XMPP, then slightly changed their implemetentaion until it was incompatible, and clients tried to keep up with changes, makes me fear meta will do something similar.
Yeah, I thought of these points too, my fear is that it won’t matter that it isn’t managed by meta and people will go along with whatever meta does.
Though to be completely fair, I have the exact same fear for other decentralised protocols, including nostr. Perhaps the only one I think is resilient to this situation is bitcoin, for better or for worse.
