Giving data to a private third party does not mean the govt has an automatic right to access it. The Constitution is supposed to restrain the Federal govt not private entities that sell your information for money.
I don't care what some black robed deity from the state has decided in the past. We already know they can and do increase power but expand it DESPITE the restraints of the Constitution.

“The power to declare war, including the power of judging the causes of war, is fully and exclusively vested in the legislature.” ~ James Madison, Father of the Constitution
“We do not believe in aggressive or preventive war. Such war is the weapon of dictators, not of free democratic countries like the United States.”~ Truman, Sept 1, 1950
