@rysiek A small criticism on this point: Multiple Relays or AppViews doesn't mean separate networks. Relays connect to PDSs and that doesn't require authentication afaik, so if you run your own relay, you by default have the same content except where the PDS went down.
(Running an ATProto Relay is prohibitively expensive for most people and Bsky could at any time lock down their own PDSs though.)
