As someone who paid (half) for my kid's college education, and who... well, let's be polite and say there might or might not be a "helicopter parent" involved in my situation, the money is large, and there's a degree to which it's less about privacy than priorities - in other words, the lines aren't always crystal clear - but I know for me, I've consciously made a decision to encourage her to fight her own battles. If she doesn't mind a filthy bathroom, that's on her.
Thankfully, a) I didn't have to worry about my kid's grades, b) her school gave me access to her grades as a matter of course, and c) I knew how to work a browser and set up a login and password (some of these parents aren't helicopters; they're clearly too stupid to fly) so that part wasn't an issue.
