The question is if suppliers should have contracts with its buyers that require use of their product to the exclusion of competitor products. This is not only limited to CPUs. This goes across the board to sodas, etc. Big buyers like Walmart have the clout to push back, but small businesses are forced to take the higher cost charged them if they choose the non-exclusive route and become uncompetitive. This is one case where the government should get involved and promote competition by allowing all businesses to be able to carry all competitive brands of suppliers without penalty of not going exclusionary with only one supplier.
