Certainly the student has wronged the university, but to my mind it's the same kind of wrong as if they'd smuggled a calculator in to an arithmetic test. That also lets the student gain a reputation they didn't deserve.
I would prefer to reserve "plagiarism" for the case where the true originator of the ideas is potentially being eclipsed.
(Incidentally, according to my local university's academic misconduct policy, if the vice-chancellor uses a speechwriter without crediting them they are indeed a plagiarist. That doesn't seem entirely unreasonable to me, though I suspect it may not be enforced, but I would prefer to use a different term.)
Would it be better to deprecate the world plagiarism and fork it into the words cheating and reputation stealing? To me, that would ultimately be more accurate, because it better encapsulates the harm involved.
