I guess the way to look at it is to ask the question, "Would I do it?" Would I, a person who is doing the public a favor by hosting an instance want to take risk in doing something which may get me into trouble. It's easier to say that YOU should do something because there is little to no risk. We got to be fair to the lemmyworld admins too and see things from their perspective. In addition, things can always change for the worst. What if these communities get even closer to actually sharing "stuff" on Lemmy? I don't know what that would look like but this is the internet and things can change very quickly, for better and most often for worse.
The nice thing about the fediverse is that anyone can create new accounts on the instances which has what they want. Why shit on the lemmyworld admins and why not just go to the instance which works for you instead? Can we all be better human beings?
Uh-oh..
