[OP] the reason I pointed that out is because public figures (reporters, celebs) can't risk that. If a server is hacked and their private key is stolen you could post anything you want as them. Of course twitter has had the same problems in the past but twitter was able to help them (usually) reclaim the account. With ActivityPub if I stole your private key there's nothing you could do to stop me until the server rotates keys. AFAIK there's no way to scrub the fediverse of tweets I sent signed with your hacked private key.
