A classic monopolist move is to use monopoly power from one business unit (such as rented computers) and offer an unrelated service at well below market rates in another market (perhaps online retail).

The incumbents don't have the crutch of the other business unit and can't price match, and go out of business.

Then the monopolist raises prices and there's no competition and no alternative.

It's fine, though google maps has gotten pretty bad; I'll just switch back to Waze.
