To be fair, PC gaming is a small fraction of the overall gaming market. All the consoles have their own proprietary graphics apis. It's ok if apple's api is proprietary too. Consoles support opengl, but it's not optimal. If they all strictly adhere to standard graphics apis, how do they differentiate themselves? Why make custom silicon with their apple 'bionic' chip? It's going to need an api to go with it.
