What makes you say that? Have you had a look at e.g. https://microsoft.com/trust ? We* are not in the business of selling your data. *I work at Microsoft
"Windows 10 is possibly the worst spyware ever made"
"Windows 10 is spying on almost everything you do"
"You still can't turn off Windows 10 built-in spyware"
"Microsoft Windows 10 has permission to spy on you"
I'm tired of this tech bullshit doublespeak. Not selling is not the same as not collecting.
