@boris So, I think @thisismissem is looking more for a group of otherwise independent decision-making entities. On the fediverse, the typical mapping is 1 server = 1 locus of control; #CoSocial and a few others are exceptions there, although that will probably change. That said, I know that the cooperative model is used in other ways than how we do it; like for independent farms that collaborate to sell milk, for example.
