Not completely true. Don't forget you need an account, for instance, to buy, install and use MS Office 360. I bet if it wasn't for the Office, many people would move away from Windows easily.
And don't forget windows comes with Defender installed, which collects user metrics out-of-the-box.
IE/Sparta also collects your usage data. Even windows "search" does.
