The idea of it being theirs implies that it (the information) wasn't mine to begin with. If it was, and I had some expectation of privacy, then AT&T may be in the wrong collecting it. Or take another path to VOIP - when your call passes AT&T's servers, if they log the bits, are they then AT&T's? Basically, if information passed to and logged by AT&T is their data, then it applies to everything passing AT&T's servers, and call content would not require a warrant either. In reverse, if there is an expectation of privacy of call data, there can/may/should be an expectation of privacy in metadata as well.
