@mcc in fact it's quite possible the suits at facebook thought activitypub was somewhat easy to game, & are only finding out now that actually, the protocol is too inherently platform-agnostic for that. & now for all we know they're scrambling to either “extend” the protocol (à la web 2.0) or adopt another one (bluesky?), or just make their own which they'll try to market to the fediverse as a “better” alternative to activitypub.
