I think 'they' have figured out and finally accepted that most 'techie'/'consultant' Linux users will also run Windows, at least in a VM, because at least some design tools will only run on Windows and many clients will insists on Microsoft Office.
They provide the 'Linux Subsystem' option for Win10 to reverse that situation, putting Linux back in the VM-box, making Widows the 'Prime-OS again :)
I think that, in the spirit of equality, my next work-only machine will be a Hypervisor (ZEN/VMware) with Linux, Windows and FreeBSD installed as VM's.
