Even from people that never lived in a communist state
edit: im 17 and i hate communism
FOSS is strongly supported by communists, but there’s also strong support for it from right-libertarians (when I was younger I remember the stereotype being that Linux users believed taxation was theft)
(I agree that the way FOSS operates is anarcho-communist in nature; I just think people with fringe politics are more likely to support FOSS in general)
