I don’t know exactly what the fedipact is, but I know of a collection of instances with arbitrary mods without accountability who have sworn to collectively create a block list and block instances based on what opinions those instances allow etc. Instances can even be blocked for not blocking another instance. I see that as a problem for the fediverse because it can grow and create an unnecessary rift of the verse.

Also, yes it’s great that you can chose instance and jump wherever you want, but an even better thing would be to put more emphasis on user controlled blocks. We can ourselves block instances from our feeds and we should make that the norm (and perhaps make those blocks more powerful and configurable if need be), and have the instances focus more on blocking straight up illegal things.
