How is this not different from asking a phone company for the transcript of a private conversation? Or of asking a bank for account statements? It is the nature of any sufficiently complex economy that private entities will possess extremely intimate knowledge about their customers, knowledge which their customers "voluntarily" provided in the course of business. None of this has any bearing whatsoever on the constraints applied by the 4th amendment, unless we are trying to move toward the interpretation that literally any interaction with the outside world is subject to unlimited surveillance by the state.
