Microsoft are clear about what data they collect in Windows 10, and I don’t have any reason to believe they are lying.
It’s a matter of trust. I don’t place any **more **trust in Linux and the FOSS community’s nebulous workings, than I do in Microsoft and the many government regulators that are itching for any opportunity to extract fines from them. If it turned out Microsoft were taking information they were not supposed to, every privacy commissioner on the planet would come down on them like a ton of bricks.
I’m pretty sure my Android phone is leaking far more of my personal information than my Windows desktop is, put it that way!
