[Impossible]

Oh I don't doubt that Microsoft politics and their "own the API" policy helped hurt adoption of OpenGL on Windows, but blaming the state of OpenGL on non-Windows platforms on Microsoft is giving them a little too much credit. The ARB was just as much at fault. Apple has had a lot invested in OpenGL, both on the desktop and OpenGL ES and in theory has just as much pull (if not more) as MS, and hasn't done much to improve the state of OpenGL either. Things have been better post ARB, Khronos does a pretty good job, especially with OpenGL ES (which still has its faults... http://aras-p.info/blog/2011/03/04/mobile-graphics-api-wishl...).

In an alternate reality where Windows is still the #1 desktop PC gaming platform, and MS adopted OpenGL instead of developing Direct3D, we'd end up with Microsoft specific extensions and vendor specific extensions to keep OpenGL up to speed with current hardware.
