Why would that ever happen? Software is too important for people to not sell outside of communism and free software people aren’t as good as making consumer products as capitalists
As for "communism" - if by whiskey, I mean if by Communism you mean soviet-union-style social arrangements, then I'm pretty sure they had closed-source software which the government controlled and people could not use and alter freely; but if you mean "communism" as in software being a "commons", then, yeah, free software will win when that is again the case.
