Nope, it’s just beehaw that independently defederated with lemmy.world and sh.itjust.works. This has no affect on communities not hosted on beehaw.

So basically if there’s a community [email protected], then beehaw.org serves as an information hub of sort for that community. All syncing between different instances goes through the original, but lemmy.world will no longer receive the beehaw syncs. If a user from lemmy.ml posts, it doesn’t come directly to us, it uses wherever the community lives as a bridge. In this scenario, because we’re cut off from the sync, we would not see any comments from users outside of our instance.

[email protected] however uses lemmy.ml as the hub. Because lemmy.world is federated with lemmy.ml, our local version is being kept up to date with the original and is not affected. So if someone from beehaw.org commented on [email protected], we’d be able to see it because it’s a different instance acting as the information hub.

Let me know if that helps, or if there’s anything I need to clarify!
