Sure. Under current law, it's not illegal, and there's nothing any Government can do about it. In an ideal world, though, what do we do with things that are not markets? In lots of cases, we artificially create a market by opening up some of the lower-level infrastructure. In the case of ISPs in the UK, we forced BT to split off the part of their business that owns and sells access to much of their physical infrastructure, allowing anyone to run an ISP. In Google's case, it might be worth forcing them to open some of the data they have to competitors. Of course, given that Google isn't actually tied to any specific country, that's impossible in practice. But what else is reasonable to do with businesses that exist in markets so distorted that they no longer function as markets?
