My counter argument is that the pedagogy is primarily with the teachers/professors and the lessons themselves. Granted, the textbooks do contain information about how to go about solving the problems. But in my experience the textbooks primarily functioned as a repository of to-do math problems. Given that math problems cannot be copyrighted, I really feel like most of these textbooks have content for the sake of making the book intellectual property and such fluff is ignored by most classes.
