I frequently see comments saying stuff like “don’t trust them, they’re from Lemmy.ml” or “I’m glad Hexbear defederated” usually in terms of tankies/pro-russia anti-Ukraine support. Or occasionally, a random dislike of Lemmy.world because it’s too much like Reddit (isn’t that the point?)
I'm certain those replies are in bad faith to discourage people from leaving reddit. The first one is obvious for your aforemention reason. The second one. I mean the internet has been around for decades. People haven't suddenly forgot how to use it. Even normies have been able to figure out how to click a server. They're fomenting lazy inertia.
The first year after the api debacle in 2023 was rife with culture class of redditors tromping through anarchist and communist communities and instances and freaking the fuck out they're allowed to exist.
Those instances have resulted in defederations or there's been enough fatigue and migration that these days its really just down to like 3 chronically obsessed users variously spamming about it.
