Google does not have unlimited. I had to pay to increase my storage.

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!

Google forced everyone off their deprecated G Suite for Business plan (which had unlimited storage) and onto a Workspace plan.

I had to give up and delete plenty of data because of this. That data was important to me, but not important enough to pay their ransom.
