Re: What about Windows 10 that Office is sitting on?
It allows you to request the information that Microsoft has collected and to demand that it be deleted or corrected. There are substantial costs associated with those activities so if Microsoft gets requests and incurs those costs it will be quick to provide opt outs rather than incur them. If you object to the data collection in the first place just ask for the information. If people don't do so Microsoft can only conclude that people don't care.
I gave up using Microsoft products after Windows 7 precisely because I do care (I now use Linux and mostly open source software).
