The reason is that they basically think Ada's the devil for not making the c/196 mod remove the "(also fuck tankies)" line from the cover image. They defederated with us, ostensibly for that reason, tho I'm fairly sure that it's because they saw the writing on the wall (that blahaj was going to vote to defederate) and tried to save face.

Anyway there's a bit of lemmy history for you.
