Lets think about it from ethical stand point. The kind of people who downloads and wants to learn is just a very tiny fraction of people in the entire tech population(Even most people in tech industry does not want to invest in learning). Their contribution will be significant. So what about the hard work the authors who had put in to create the course ? Don't worry their life will not be affected much(not like they will miss being billionaire). The only people who might get affected is the undeserved people who is taking advantage of intellects like the university.
