How about we perform a basic statistical analysis and see what locations you frequent. From that we can tell what religious, financial, and social organizations you are a member of, and can go beyond to what stores you patronize. And what routes you take to and fro. Metadata can be as harmful as recording the calls, if not moreso. Betcha they collect more than just the raw call metadata, and collect metadata on data connections. From that they can more easily determine the above, since you don't even need to be on a call for a service to connect to the 'net.
