Yes, you’d be a fool to believe MS customer experience programs would result in your data being misused.
They didn’t hand out Win 9 for free and push the software through security patches and make it hard to remove because they would somehow get compensated selling your data.
They did it because they are so nice, friendly, and thoughtful.
That's true. Same for Windows 10. :-)
