It is a FOSS, complaining about proprietary APIs, because there is this dissonance between communities.

Game developers care about IP, how to make it go beyond games, getting a publisher deal, gameplay, the proprietary APIs is a set of plugins on a middleware engines in-house or external, and done it is.

Also there is a whole set of companies whose main business is porting games, where is where several studios got their foot into the door before coming up with their own ideas, as a means to get experience and recognition in the industry, they are thankful each platform is something else.

Finally anyone claiming Khronos APIs are portable never had the pleasure to use extensions or deal with drivers and shader compiler bugs.
