This is blatantly false. You may be thinking about OpenGL 1.x and the fixed pipeline. Modern OpenGL is perfectly capable of running virtually every game and professional app out there. OpenGL does NOT work on macOS and hasn’t worked for a very long time. Apple only allows to use an ancient version of OpenGL, which is not really my definition of “working”. Nobody is going to ever remove OpenGL from Linux (or Windows) drivers. OpenGL/D3D powers everything there. Vulkan and Direct3D 12 are just the lowest level and are not a replacement for OpenGL nor Direct3D 11. Drivers may implement them on top of Vulkan/D3D12, but removing? Never. Finally, Apple has never told anybody to use MoltenVK because they don’t want you to. And I would not be surprised if they end up banning such layers if they find they get popular.
