> Abusing your monopoly power is however illega However the principle that underwrites all of it is harm to the consumer. If you can't prove harm then it is hard to justify action. If consumers are choosing the monopoly provider willingly with zero compulsion by factors other than that it serves them well then you have a good argument that the monopoly is not harming the consumer. The best argument would be that the purchasers of advertising are harmed because Google's ad prices are bolstered by their monopoly on search. However even there, Google uses a quite transparent and open bidding system for ads. They have no direct control over what people pay, they don't set their own prices - Google only shows ads at the prices people voluntarily bid. This doesn't put them in the clear but it makes it pretty hard to prove they are gouging or any of the other obvious signs of a monopoly abusing their power.
