it’s more correct to say they’re on lemmy than kbin though… they are interacting through lemmy: kbin is literally irrelevant to them
… and that’s kinda the point of the fediverse isn’t it? you shouldn’t care where something is stored, and if you don’t care where it’s stored then you have only 1 way to refer to the space: the client by which you’re viewing it
people referring to it as “lemmy” or “kbin” or “mastodon” is the fediverse working as intended, and that’s good news!
(it’s also much better marketing for us! people search fediverse and they get a bunch of random descriptions about what it is… people search lemmy/kbin and at least they have a join button)
