I understand abstaining from a platform on principle. But it's pretty simple to opt-out of non-essential telemetry because so many people complained about it in Windows 10: https://www.windowscentral.com/how-view-and-manage-diagnosti... I set telemetry to 'basic' which means I'm comfortable with essential system data being sent in return for my system gaining updates and security patches. Microsoft does a better job…
There is no such thing as essential telemetry. There should be an option to turn it off completely.
It would seem the only route to privacy, in such a world, is to never interact with their servers at all; which means never receiving updates; which makes any OS into a lame-duck product vulnerable to all manner of exploits; which probably means you should just never touch a computer in the first place, "to be sure."
