Trump’s Truth Social is based on Mastodon (even if with federation and syndication disabled), and the POTUS Threads profile iirc has ActivityPub enabled. Also wasn’t Germany that also adopted for some government profiles fediverse-compatible services? Or some other EU country. Still, if the neighbors and ideological allies of Canada already tapped into such projects, I’d say it’s no longer uncharted territory, and so the possibility is there.

'twas a good conference 😁
