Linus is very anti-GPL3
Quote: "In a very real sense, the GPLv3 asks people to do things that I personally would refuse to do. I put Linux on my kids computers, and I limit their ability to upgrade it. Do I have that legal right (I sure do, I'm their legal guardian), but the point is that this is not about "legality", this is about "morality". The GPLv3 doesn't match what I think is morally where I want to be. I think it is ok to control peoples hardware. I do it myself."
