It’s the Fediverse. Part of the whole point of a distributed network is to decentralize things, so there is no “single point of failure”, the existence of c/opensuse on lemmy.world, or any other lemmy instance, or even m/openSUSE on any other kbin instance is perfectly fine. These are the early days of “reddit-like” federated services, and the interoperability will sort itself out in time.

I’d personally like to see the communities on other servers commit to the same rules this one does, but it isn’t actually necessary, it’s just the very basic requirement to be considered “Official” Not that Official means much in the openSUSE Project. It’s just the nature of us.
