Hah, yeah. Mostly because of each side's interests: the job of the administration is to sell the idea that $university's degrees are a valuable thing you should want, so it is completely crazy to them that you don't want their degree. But the profs ideally want to teach stuff they think is important/interesting to people who want to learn it, and to them, the people taking the class only because it's required for the degree are sort of the least desirable students, while someone taking it even though they don't have to, because they actually think it's interesting, is great.
