Universities are the source of huge amounts of lines of code and also of graduates that, later on, will be the ones writing code. It's essential that, as soon as they are exposed to the act of creating software, they also are explained that software can be free (and, in fact, it can be argued that it should be free) and that they, themselves, can make it free. Not only that: university staff and professors and researchers have to be given the opportunity to adopt the libre software philosophy in their use, acquisition and development of software.
