You mean like forcing kids to buy brand new books so that they can get a code to use to take tests on an online platform that the professor gets kickbacks from that has nothing to do with the university the kid is attending?
I don't see an example of how the university is losing revenue and being defrauded in that scenario.
Leaving aside the legal issues (I'm not a law expert, so I don't know if it is illegal), don't you think it is incredibly immoral for a professor to require a specific book for their class on the basis that the publisher is going to hand a check to the professor?
It's telling that you were more willing to make sure the university wasn't being defrauded but I guess the student can kick rocks right?
Similarly, in the case of college admissions scandals, it is the college being defrauded.
Now here, to make a parallel as you were intending, we'd have to see how the university is being defrauded.
