How the tech titan plans to argue that it’s not a monopoly.

Antitrust actions have a nasty way of dragging these sorts of internal deliberations into the public eye. If Google can keep its antitrust fight to market definition, it wouldn't have to worry about addressing questions about its auction pricing, its partnerships, and its methods of determining relevance. If it can't, it will have a lot of explaining to.

"How at the end of the day do you prove that Google didn't do something nasty to disadvantage a particular Web site?" Wagner asks rhetorically. "We've never done anything like that, we don't have an interest in doing that. But it's a hard question, because if you want to know what people are thinking, that's what litigation and discovery are about."

Exactly.
