I'm not sure how many people we employ. (more than 15k) and we're all using windows 10 without telemetry enabled.
However, I'm relatively sure that this is due to the efforts of our very talented Windows Systems Administrators. Nonetheless, it's possible.
Nevertheless I do think this is different since management defers decisions about software versioning and life-cycle management in general to developers. I do think this will cost them some hard earned customers.
Certainly a bad move and I doubt it will amortize.
