You can try to get away with the classic "I use Arch btw." Either they are seriously impressed and don't ask any further then, or you fucked up completely.
Zucks poor attempt to connect his Meta bullshit with the fediverse. It's desired to be a Twitter replacement which uses the ActivityPub-Protocol and therefore is able to communicate with fediverse instances (which use the same protocol). So basically it's the same as Mastodon, just with Zucks closed source corporate crap.
Quality content, ngl
