The statement was
What is it about the lemm.ee domain that produces accounts with the most cringe, awful takes?
Now, I wouldn't say that's really appropriate here, Dagwood222's comment above that wasn't cringe nor awful. However, apparently UnderpantsWeevil already has this perception of lemm.ee users, and hexbear users making up a chunk of the userbase is my explanation for that.
No one ever really spoke bad of lemm.ee users before the hexbear defederations, and it was a clear echo of the complaints about lemmy.ml users that also started at the same time. It's just a bandwagon/circlejerk, really; a cheap way of getting upvotes from other users not on those instances that only has a pinch of truth. But that pinch is what I was describing.
Did you read the article? The GrapheneOS devs are saying the exact same thing as Google here...
Personally though I wouldn't trust the GrapheneOS devs much, they're a bunch of divas.
