That's quite different on the first bit, an OEM choosing to only supply one company isn't the same as a major company offering bribes or incentives to not use a smaller competitors products, one is a business choice and the other is breaking antitrust law through "unfair competition" as a result of undermining the free market
(and it's hard to say there isn't legal precedent on that).
Second bit is completely true though, Intel has long offered hefty amounts of extra support to OEMs as an incentive, a significant portion of their revenue and expenditure is from services generally though.
