I guess you’re unfamiliar with that user but basically their entire Lemmy existence is just arguing with people about the things they own or use because “my thing is better”. They are very active in privacy communities and constantly start pointless arguments by being needlessly oppositional whenever someone dares to recommend or even discuss something that they don’t personally use. I don’t think it’s trolling or bad faith, I think they just genuinely have real difficulty seeing the world from any point of view other than their own. Hence this idea that Grayjay can’t possibly have users because people enjoy using it - there must be some other explanation, like that we’re all Louis Rossmann fans.
