Why YSK: Beehaw defederated from Lemmy.World and Sh.itjust.works effectively shadowbanning anyone from those instances. You will not be able to interact with their users or posts.
Edit: A lot of people are asking why Beehaw did this. I want to keep this post informational and not color it with my personal opinion. I am adding a link to the Beehaw announcement if you are interested in reading it, you can form your own views. https://beehaw.org/post/567170
You said yourself that Beehaw is one of the largest communities. They aren’t struggling for users, despite stricter rules and de-federation. If you actually read the announcement threads about the de-federation, Beehaw users love it and are very supportive of the decision. The outrage seems to be entirely generated by people who aren’t members of that community, so who cares? If you’re that unhappy make your own community (or cry) but don’t pretend it’s the responsibility of Beehaw to pander to non-members.
And to the overall growth concerns, again - who cares? Lemmy doesn’t have to be a 1:1 reddit replacement. I’d say many of us actually consider it’s relatively low user count as a positive.
