" In its 2009 ruling the Commission, the EU's top antitrust authority, found that between October 2002 and October 2007 Intel sought to exclude its main competitor, Advanced Micro Devices (AMD) from the x86 processor market.
Then with a 70 percent share of the worldwide x86 processor market, Intel granted exclusivity rebates to four PC and server manufacturers, Dell, HP, Lenovo and NEC, the Commission found. Intel also made payments to Media-Saturn on condition that the German distributor sold PCs with only Intel processors inside, the Commission said. The rebates and payments made it harder for other chip makers to compete, reducing consumer choice, it ruled. "
Yet Intel could literally give away their mobile and Itanium chips for little or nothing to lock out competitors, and it's totally legal. Notice how since Intel stopped doing that how many lower cost devices, such as Android tablets, are now using ARM.
