I don't think so? The keys were given to students but afaik they are intentionally valid past graduation and transferable to new machines via microsoft account.

Edit: perhaps you misunderstood - I didn't take keys that were licensed for university owned machines, I got a key that was given to students for their personal devices as part of some agreement with microsoft.

Although I have no qualms about actually pirating windows either ever since they started pushing advertising into the start menu.

MSDNAA allows using the software after no longer being a student.
