Why have a discussion about PC's and gaming as gaming is just for consoles, not personal computers whether it is Windows, Linux or OS X.
How many games hit Windows PC's, not many compared to the console market, how many games hit OS X, not many as OpenGL is dead, how many hit Linux, not many because of their open source attitude and OpenGL is dead.
Why discuss gaming on PCs? Because companies make a lot of money releasing games on PCs.
How many companies make money releasing them on OSX and Linux?
And is that a reflection of OpenGL or a reflection of the market?
If OSX and Linux games sold you'd see OpenGL being relevant. But they don't sell. Not enough people care about them.
Gaming wasn't common on those platforms when OpenGL ruled the day. It isn't common now. OpenGLs rise and fall had nothing to do with it. But the failure of gaming to latch on to those markets clearly has something to do with the fall of OpenGL.
You need to reinterpret the cause and effect.
