Unless there's something particularly different about University of Minnesota compared to other universities, something tells me that they won't give a crap unless you're a donor.
"Yes, we are banned from submitting patches to Linux due to past academic research and activities of our PhD students. However, we have a world-class program here."
Getting banned from Linux contribution is an ouchy for the university, but the damage has been done.
I'm glad I never contributed again as an alumni...
If enough grads do that, I would expect the university will do something about it, and that would send a message. It's about where the money comes from in the end; (tuition, grants, research partnerships etc) IMO none of these sources would be very happy about what might amount to defacement of public property and waste of the time of people that are working for the good of mankind by providing free tools(bicycle of the mind) to future generations.
There is no novelty in this research; bad actors have been trying to introduce bad patches for as long as open source has been open.
