Google Drive reneged on unlimited storage for Education accounts once they realized that universities also contain researchers who need to store huge amounts of data.

Not only did they cut unlimited, they went to insultingly low limits with not much warning after all their nice promises. Moderately large universities ended up with less space per student than the 15GB they give out to anyone for free. It was a pretty bad rug pull.

Massive fraud from abroad didn't help there either. A favorite backup spot for terabytes of pirated media, complete with guides on which schools had good @edu addresses for it.

Hadn't even considered your obvious point, a good one!
