Nobody is placing restrictions, but it's understandable if people are skeptical.

> Whether a professor teaches from his or her text is largely irrelevant.
If a college professor writes and teaches from a book, he's requiring people to buy it. That often gives him royalties, which is a perverse incentive. I wouldn't call this a fat scam, but it's probably relevant to the idea that the textbook industry has some issues.
It might be worth distinguishing between college and public schools, where the burden of cost is on either the student or the public.
