And so if you try installing the Bluesky app, how many relays does it have? And in Mississippi you now won't be install the app or you won't able to use the bluesky relay either?

I'm coming from understanding nostr - each app usually starts with ~10 relays and as you start interacting with other people it collects more paths/routes/relays (the new "outbox model"). So as soon as you install any nostr app, it's usually not affected by any single relay issue.

This does not require the bluesky app. I'm not in Mississippi, but people on bluesky are reporting that these alternative AT Proto apps work fine there and grant full access to the same content.
