Isn’t X-Plane on Linux?
That was last year, i think. Not sure how that would be related, though. IBM bought Red Hat to get more traction in Cloud Services (which is all Linux). Officially the thing with DirectX is to make things easier for tools that run a GUI under Windows Subsystem for Linux. To me, the DirectX thing is just as much an oddball as is the entire WSL thing, though.
@staff Could you do us a solid and split this off?
