I wonder the same; is ActivityPub lucky because there's been reasons for communities to swap over, or is it doing something better? If I'm thinking of Mastodon is a Twitter alternative, I sort of think of Element as being primarily a Discord alternative, so I guess if Discord went really bad it would be easier to test that theory?
