Every instance has somebody who manages it, sometimes that's an organization...now I don't think Meta would like to buy #JournaHost, I mean if they wanted to get looked at seriously by journalists, sure, they could do it.
#Mastodon may already be too big, that if they wanted to buy everyone, it would be a lot of people to "buy".
Also how would it happen? Would they try to employ everyone?
At what salaries? Just cause you got money, doesn't mean #InfiniteMoney.
