At work they forbade the use of one drive. It literally was consuming hundreds of terabytes of data and many more on bandwidth because they activated auto sync on thousands of laptops after an update without telling anyone. It was synching entire hard drives of confidential information without our consent. By the time our IT realized, they were trying to charge us for it (web do have SharePoint on azure). Turns out there’s some you can disable by group policy, but the shit is so embedded that it cannot be completely turned off. So they are just instructing workers how to avoid it now and warning everyone that, although we do have a quota per install of one drive, any loss of data is the worker liability as we are being told not to use it. Microsoft is such a joke.

We are facing similar issues with copilot by the way.
