Yeah. I don't understand this. Lemmy is an open source software and there are many instances to use. Hell, lemmy.ml is even pushing people away from their instance - that doesn't sound like people promoting lemmy to advance their ideology.
Don't agree with the devs' POV, use a different instance. I'm not socialist/communist and I'm perfectly fine using lemmy. I've talked to the devs and they've been nice and polite, and I haven't really encountered any lemmy.ml content trying to poison my mind. Lol. We even stayed on reddit even after fucking jailbait, the Donald, etc. fiasco.
