I’m not just talking about M$, most software and hardware should support Linux officially. And support also means making the usage with Linux easy and robust, having official instructions for Linux, being able to return it if it doesn’t work with Linux, and so on.
Tuxedo and System76 are exactly what we need imo, but at a much bigger scale. I want Linux to be on almost every PC and laptop, and that would mean every major OEM supports it.
