There is also a question of Intel's purpose in changing the bus.
Intel's old South Bridge interface was called Hublink. As is usually the case, things evolve. They moved on to DMI (Direct Media Interface?). Technically, neither Hublink or DMI are busses as they connect 2 and only 2 agents directly. If I understand things correctly, Nvidia claims it has a DMI license. Intel says it doesn't but they could have one for a price.
They have already practiced anti competitive practices and at the same time denial. It has been shown and documented, their purpose.
No Court of Law has ever concluded that Intel practiced illegal anti-competitive practices. I know you want to claim it's documented but only allegations are documented. There is a difference but I wouldn't expect you to know it.
