Let's show some figures regarding how much money gsync modules actually contribute to the bottom line. Until then, it's much ado about nothing.
It's not about the money, it's about the branding. There is good will in interpolation and VRR ... and there is no pressing need to ditch that.
If they become aware of say Intel cooperating with some major tent pole game to force the issue, I'm sure they'll try to head them off at the pass. If VR keeps growing slowly, that might do it too ... eventually.
