hello. can confirm. I'm on kbin.social right now and seeing this thread. I'm not sure federating is entirely up just yet but it's working a lot better/faster than it was these past few days. Definitely seeing an influx of beehaw and lemmy world users and posts :)
I'm kinda shocked they're openly saying "I just don't like [lemmy.world's] vibe" as one of the justifications, as that looks like the slipperiest of slopes.
I don’t think it’ll end well for them, and it’s a disappointing choice. However, choosing to not federate is just as much a part of the system as choosing to federate. If everyone had to run exactly the same setup we everyone else, the whole thing would be pointless.
