He is not wrong. I have had to block and get rid of other instances on Lemmy, because they are filled with toxic motherfuckers, and elitist Linux users
I'm so intrigued by how often people complain about foss and Linux on lemmy. Everything about Lemmy appeals to people who are really into both and as someone else pointed out those leanings and the other main complaint, leftist politics, are all insanely tied together and all should be very much expected on Lemmy.
