 One can disagree with Friedman's views, and he himself changed his views over his lifetime. He emphasized the importance of discussion and debate. But I don't think you can question where he was coming from in the sense that he really was trying to increase human freedom, capitalism and freedom, free to choose. When writers are talking about freedom in the title of their books, it's really important to them. Maybe he didn't get it right entirely, but that was his goal.
