I'm not sure how Linux's viability as a desktop OS is relevant to Windows being usable or unusable.
I have no idea what else they've installed, just like I have no idea what MacOS or Linux install. They're all black boxes to me. I see no reason to think Windows is any worse than it's competitors.
I assume by spying, you are referring to Windows 10's telemetry. Personally, I think concerns about it are overblown and calling it spying is misleading at best. It's for diagnostic information. You can set it to only send basic diagnostic data if you so choose. I am in favor of companies collecting diagnostic information about their products to improve them.
