"To do this, Google said it had obtained access to the credit and debit card records of 70 percent of U.S. consumers." <<< If that in not illegal -- it should be.
They might have access to peoples' purchase data of Google sold products and transactions made with Google wallet or other processing they control.
I think that statement is bullshit.

Don't buy from Google and they cannot access your data from other credit card processing sources outside of the Googleverse AKA E-Corp ;)
And you wonder why people block ads?
