This is precisely how things worked back in the days of FidoNet, and it was one of the big arguments that was never fully resolved, as you had one group of sysops who felt that if you wanted to be a FidoNet sysop you should be obligated to carry whatever topics are on the network backbone, and another group of sysops who felt "my computer, my rules". Fundamentally it was a disagreement over what being part of a federated service meant. Such disagreements eventually led sysops to leave the network and start their own. I have little doubt that is going to happen with the Fediverse as well since some nodes seem hellbent on making sure it happens.
