say there are three instances, A, B and C. if A is not federated with B, users from those two instances can’t interact (right ?) but what if both are federated with C ? would both indirectly be able to interact ? if there is a post on instance C and a user from B comments on it, would that comment be visible on all three instances ?
I think they are using it exactly as intended, the software is specifically designed to be decentralized and gives instance admins the power to de/federate as they choose.
Let’s say when meta releases their activitypub thing, should everyone federate with them just because they are on the fediverse and will likely have a lot of users?
