Not really related to this but since the 80s one of the arguments, pretty much always ignored, was that open source is evil because open source is communism. I occasionally hear that well to the present when you explain a bit of software someone can use to handle something they're trying to handle and that it's open source and free so save them some money and you explain what that means and they dismiss it in disgust because, "that sounds like communism to me"

edit: Also it's not just old people. It used to be almost nothing but old people but I've noticed a significant uptick from young people that are open source communism, spit. Not as bad with tech students. Ones that aren't in a tech related degree program or not in the industry, way more frequent disgust towards open source software because open source is a security risk. Easier to hack and damn communism. YouTube university. I partially think it's anger that all their software money making ideas have pretty mature open source solutions and they're bitter that all the low hanging fruit is done and the new stuff gets open source solutions pretty fast.
