I read that they “defederated”… What does this mean? And why did they do this? And what are the consequences?
I don’t know the why, but the word “defederate” refers to an instance ceasing communication with other instances. That means any posting, commenting, or messaging, no longer works across the connection between that instance and others.
Basically, to everyone on beehaw, the rest of us have gone silent, to us, beehaw has gone silent.
… to us, beehav has gone silent.
Beehaw hasn’t gone silent for us, see https://lemmy.world/post/149743 for details. Other instances haven’t (yet) defederated Beehaw, so things behave asymmetrically.
Indeed.
They defederated from lemmy.world and sh.itjust.works

Yes but defederation is a one way thing. Not two way.
Beehaw defederating Lemmy.world doesn’t mean much for Lemmy.world because they haven’t defederated beehaw. Users on Lemmy.world can still see posts and comments from beehaw, but users on beehaw cannot see posts and comments from Lemmy.world.
The only issue for users on Lemmy.world is that if we comment on a post on beehaw, none of the users on beehaw can see it. Users from other instances can though.
