One way to get everyone in a university on the same page is to punish them all for the bad actions of a few. It appears like this won't work here because nobody else is contributing and so they won't notice.
It's not the number of people directly affected that will matter, it's the reputational problems of "umn.edu's CS department got the entire UMN system banned from submitting to the Linux kernel and probably some other open source projects."
