Ye good ol' Microsoft stiffled OpenGL on Windows, hence open letter https://www.chrishecker.com/OpenGL/Press_Release not to mention insidious thing they did on Fahrenheit (next gen OpenGL+Direct3D, one to rule them all) when they were supposed to be working on it together with SGI. Microsoft did a well job after with it, but they were and are a shit company that made sus maneuvers to make success; Not all of them technical.
