This video is very far from giving the actual "Why". The actual why is not that Microsoft uses paying customers as beta testers to save money (since Microsoft obviously has SO MUCH LESS cash than the average user). The more fundamental why is somewhere within Microsoft's unilateral, brain-dead, and absolutely unforgivable corporate decisions to (1) effectively ship without testing and (2) pretend that their various platforms are equivalent when of course they are not (737 MAX, anyone?).
And nothing in this video explains, for example, why Microsoft intentionally kills paying customers' USB ports in the middle of the night, their latest "gift" to astronomy. What the video does explain is: the best and perhaps only defense against Microsoft's boneheaded decisions is for the user to do clean install after clean install. Microsoft just washes its hands of responsibility. Absolutely unforgivable.
EDIT: and now MS + Linux? Great combination: all the incompatibility of Linux with all the reliability of Microsoft. Oh. Yippee.
