We're not talking about Microsoft's cloud / server strategy though. Linux as a server OS is different from Linux as a development platform. The two have nothing in common except the word "Linux."

Microsoft is taking steps to embrace desktop Linux, we've seen that with WSL. Instead of ditching Windows for a different/better dev platform, just keep using Windows.

They are extending their own desktop Linux by adding the capability to use DX12 in Linux, so long as it's run on Windows. Note that they are not adding this capability to a straight Ubuntu install, let alone any other distribution.

To claim "Microsoft knows they can't Extinguish desktop Linux" is naive at best, and shill-like at worst. They don't need to completely eliminate desktop Linux for EEE to apply here. the "Extinguish" part comes naturally from fewer and fewer devs choosing an alternative to Windows.
