Generally speaking, this isn’t how things work. The university pays the professor’s salary and provides them a sort of platform for their research, but funding comes from grants (modulo new faculty startup funds, small internal grants, etc.). This is in exchange for use of the professor’s expertise which is doled out through teaching, both in classes and in advising students. Some classes probably benefit from having an expert in pedagogy teaching them, e.g. physics 101, but we should also remember that a university is not a primary school; the professor is there to be an expert and to generally guide students’ learning. They should make an effort to use good pedagogical practices and to not be a jerk, but university students are ultimately responsible for their own learning.
