I doubt that - in the other thread, someone noted that the last non-hostile kernel contribution from @umn.edu was in 2014. I don't think they are champing at the bit to get legit kernel contributions merged - or at least haven't in the past 7 years. At this point, it is purely a reputation/PR problem with little urgency - the ban is not blocking anyone's work at the university (except for the suspended research project)
For now I'll accept their apology, but if there is no action in the future I'll retract that.
The common case today is that admitting you are due to account for your actions is the same as admitting that you are at fault. I have been denied jobs because I have admitted that to being accountable for my decisions, whereas I got the distinct impression had I simply not accounted for them they wouldn't have cared.
They need to act to get the ban rescinded, they can't just ignore this issue away.
