You are either being dishonest or are just ignorant. User data is disclosed to advertisers when they auction for ad placement. Many of those advertisers then sell the user data they collect through the auction, whether or not they win the auction, to other parties. It's a virtual certainty the FBI, CIA, NSA etc purchase that information.

Your argument is basically Google didn't do anything wrong because they are not the direct point of sale. But they aren't fools. They know what happens to the data they disclose to advertisers. It's repackaged and sold again.
