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

DeAr Mr GaYwAllEt, PlEaSe lEt Us TaLk oN Ur EcHo cHaMbEr. PREEEEESE

Fuck'em. No one wants to talk to a bunch of sensitive sissy men anyways.

🤣🤣🤣🤣🤣 better watch out, being sassy will get you a spanking.

How dare you not consider the feelings of the billions of people on planet Earth that use the internet. Absolutely preposterous
