It isn't that. it is that people think, for soem reason, that they are supposed to like D&D because it is D&D, and when they don't, they don't know who to process that. When you are talking about good games that are lesser known or played, no one feels compelled to liek them. if you don't, you don't, and you just move on. but twith D&D, we feel like we have to explain why we do or don't like it, and then defend that against those with differeing opinions.Or maybe it's because those are small fry in the world of TTRPGs compared to 5e, and elements of "fandom" culture make it cool to junk on something when it reaches popularity with the "wrong" people.
TTRPGs, as a industry and hobby, would be better off without D&D for this reason alone.
