"Now I don't think socialism is a dirty word, but saying Open Source is socialist is wrong. If anything it's extreme Libertarianist. It's saying if I give you something, you can do whatever the fuck you want with it. Open Source is not about the government, or any other organization, providing institutionalized software for the good of all."

Open source may be this way, but the GNU (which Wordpress is licensed under) isn't.

The GNU license makes it so everyone is equal. Nobody can have any competitive advantage over another, because as soon as you do, everybody else can now have your code.

You also can't do anything you want with it.
