This has been a major pain point for the Linux community since the Radeon days. It's such a shame, because ATI had a huge opportunity to steal that market from nVidia back then. Instead, maximizing value away from users and toward shareholders left us with a video-diminished Linux community.
Given how many thousands of dollars we steered to Intel because of it, I'm not sure this maximized shareholder value either. Few things businesses do are actually big-picture decisions.
