Actually, that's false. Most of the money Google makes from ads are not behaviorally targeted ads, but keyword targeted. If you subtract out YouTube 'behavior target' which seems more targeted based on what you watched, the portion of money Google actually makes from using 3rd party website tracking is quite small.
