what does it mean that Beehaw "defederated" from lemmy.world? - Lemmy.world

I thought I understood, but I still have Beehaw content in my feed, so I guess I don’t understand after all… Can someone dumb it down for me?

Lemmy.world still has all the content it pulled from beehaw before they defederated, but they won't sync anymore, so you won't see new beehaw posts, and they won't see any posts, comments or upvotes from lemmy.world
Was there a reason why they defederated??
someone got butthurt it sounds like.
Maybe we need to write them an apology letter in their sign-up to rejoin.
Gay fuck that
Comments like this... now I understand why they defederated.
I'm not kissing your, or anyone else's ass. The fact that a lot of you Embrace and encourage other people to determine how other people should behave, is a jackass entitled way of thinking.
Your profile pic is really cool. I didn't know you could use a gif as your profile pic
I didn't either. I discovered it by accident.
