You're getting blasted for this because people don't want to hear it, not because anything you said was wrong.
The only part I disagree with is the 90s style wild west theme; that would require competition of which none will be able to grow. It's impossible to catch up to where high end GPU market is right now without an insane investment that could never be recouped. Why would ANYONE bother spending billions trying to white-room a new competing GPU architecture from the ground up just to slip into fourth place behind Intel's 1% market share? Especially since, as you pointed out, the established players don't have to follow any laws especially when it comes to buying up and dissolving any and all competition in their field.
