Unfortunately, that’s the wrong thinking. There are different kinds of mods for controversial topics. Let’s say: UFOs. Mods on one lemmy instance might allow only sightings (that’s the deal with the reddit one, for example), but another one might allow also for abductions (as it should, since it’s part and parcel with the whole thing for many people). So disallowing communities from existing on different servers, it controls the narrative and creates pigeonhole opinions. It needs to be something for everyone instead.
