IANAL, but "reasonable expectation of privacy" sounds like a default position when no expectation has been set between the customer and the service provider. In this particular case, there was an explicit expectation of privacy set out in the terms of service, and in fact that expectation was the entire justification for charging for the service amid a proliferation of free competitors. Of course my interpretation could differ from established case history, or even with a technical legal reading of that particular clause, but there seems to be a logical argument there (whether or not there's a legal one).
