So I guess you don't believe in private property rights.
These records are still the property of the donor, and the donor has the right to do whatever he wants with them.
When he transfers ownership to the University, then it's up to the University to decide.
If the University seems to be bending over backwards to please the donor, well, that's just common sense, when you want more donations, you don't want a story going around that a donor is sorry he donated to the University. That could inhibit future donations.
