It's chicken and egg problem. Nvidia was major backer of OpenGL, but their drivers were never conformant implementations that allowed a lot of incorrect shaders to compile and run. Yet Nvidia had best developer support so most of commercial apps were developed and tested against their drivers. As result those apps use non-standard codepath that simply dont work on conformant drivers. On top of that OpenGL compatibility contexts are not well documented or tested, but it's not strictly Nvidia fault. In case of Wayland it was was opposite. It was developer by everyone, but Nvidia. Open source graphics stack developers found a way that work best for their hardware and supported it for decade. Recently Nvidia tried to join the parry while extending it with own incompatible addition that no one else needs. Obviously many open source proponents dont give a damn about their closed drivers so they only going to support primary APIs.
