I'm actually shocked and disappointed by this. Why valve? You made a sick operating system. Dedicated countless hours to development on Linux. All this to get away from the Microsoft monopoly. Now, you're dedicating more hours to the support of Windows? Will this be installed on the Steam Decks by default? What is your plan?
It's literally just drivers that enable user choice. Steam OS is great and nobody reasonable is switching, but for those that do it's good that they have support for the hardware.
