> Monopolies can only be created by government dictate, like old AT&T or modern cable companies.

By virtually every definition I can find, a monopoly is a an entity that functions as the sole, or effectively the primary, provider of a good or service in some market. That seems to perfectly describe Google’s position wrt web-based advertising. Do other ad-platforms exist? Absolutely. Do they exhibit the kind of market dominance or control that Google does? Nowhere close.

> Google has no power to stop them.

Fact? I’d argue that Google’s sheer size and dominance means they don’t need to stop them. Potential competitors simply don’t stand a chance given Google’s size, number of resources, and reach. Explain how that’s not a significant factor into Google “power to stop” a potential rival?
