Open source isn't counterculture anymore, sorry but it has gotten too big to fit in your backpocket.
I understand you disagree with some of the people using and writing it now... but if that's the case, perhaps communities using a different kind of license would be better suited for you if you cannot get along with them?
I feel like the author is trying to point out some kind of hypocrisy while also feeding into one themselves... if open source was supposed to be for everyone, well, that includes people you don't like. And you're not going to change their opinions any more than they can change yours.
