Regulation

FTC doesn't go after Google (and shouldn't have).

"Previous attempts to go after big companies — such as the Justice Department's long-running antitrust case against Microsoft in the 1990s — loomed large in regulators' minds at the time of the Google probe, according to a former official who worked at the agency then. "Even if we were in the right and could win," said the former official, "it could take a lot of resources away from other enforcement.""

Less burdensome regulation for the big guys, more for the small guys.
