They are reimplementing the Linux kernel in the Windows Subsystem for Linux (WSL). It's easy for them, since they have access to the Linux kernel source code.
The wine project or ReactOS reimplement NT and some of the WinAPI. However, they get no support at all from Microsoft.
They could support those. That would be a gesture of good faith, in my opinion.
Completely agree, AMD, Nvidia support opensource, like by publishing their hardware spec for free, contributing to Linux kernel. Google does it somehow with GSoC and releasing tons of libraries. But really Microsoft? Did they do anything meaning? Did I miss anything? All they do is good PR and suits behind our backs.
Microsoft research have contributed significantly to advancing the state of computing going back to the early 90's. So sounds like you have missed a lot.
