Microsoft is selling to your employer. Google is selling you.

I’m kind of inclined to give MS the benefit here.

One where they collect and sell an order of magnitude less data. Maybe 2 orders of magnitude.

lol have you heard of ... Windows 10? No OS collects more usage data. And no you can't disable it. And if you try, it will re-enable tracking after some updates.

Have you heard of… Google? Search, Gmail, Maps, Android, YouTube, Smart Assistants, home security cameras, thermostats, Chrome, and more, and more, and more.

I’ll stick with my assertion that Google collects 1-3 orders of magnitude more data than Microsoft.

Those are services not OS. And Microsoft services are no different. Difference is that Google is more successful (has more users and services and therefore more data).

MS wants to sell software. Google wants to sell ads.

Right, a "vendor" is someone who sells something.

Microsoft is a the world's largest spyware vendor because Google gives their spyware away for free.
