Users of different appviews are just using a different aggregator/backend in effect. The network is still largely the same but there may be minor moderation or feature differences between appviews.

Users of different PDS would be the closest thing to a mastodon instance and there's thousands of different PDS without much issue. I'm on a "third party PDS" and I've had barely any issues.

I use a "third party" PDS, appview, PLC directory mirror, CDN, and client so 99.9% of my interaction with bluesky and atproto at large is independent of bluesky the corporation.

Despite using a third party "basically everything" my experience is essentially the same as a "default" bluesky user if not better in many ways
