I'm in university (as an old) and just about everyone from faculty to staff has been pushing me to put everything in OneDrive. I know better, but young people tend to trust that an educational institution is looking out for them.
My freshman year I met teenagers who didn't know what a flash drive is. Most of them have iPads with no storage, one of my classmates was just uploading all her lectures directly to YouTube so she could review them later.
Yeah, I understand why employers use it. Oddly, I used to work for Microsoft and can't remember using OneDrive for our projects lol
But as a student I really prefer saving stuff locally and to a separate storage device. The university system has been hacked at least once since I've been a student, we all lost our credentials and were required to physically go to the campus to reset them. The university also revokes access three years after graduation.
