Uni of Minnesota earned themselves a ban from contributing to Linux Kernel due to unethical behavior of a group of their researches: https://lobste.rs/s/3qgyzp/they_introduce_kernel_bugs_on_purpose
Another related story from comments: https://github.com/lobsters/lobsters/issues/517. The latter is particularly damning, as the "researcher" once their bullshit was uncovered tried to make it look as if the problem was with the maintainer's "hurt feelings". Which the latter handled rather well :-)
