If Google’s a monopoly, who is harmed by its market power?

Google has long defended itself against charges of monopoly by stressing that its products are free and that no one has to use them.

And it’s avoided tough government scrutiny for years based in part on the idea that people searching the internet are not Google’s true customers.

We’re its product. Advertisers are its real customers. That complicates the question of who, if anyone, is hurt by Google’s dominance in selling ads off the world’s search queries and through its array of affiliated businesses, from its Android phone software to its YouTube video platform and digital maps.
