Matt nailed it. Metadata is an old science. Not that long ago it’s all there was readily available (say without a tap), and that went on for decades. Protocols were developed to study life patterns through telephone use. All kinds of clues were used. For ex drunkenness could be detected by repeated misdials. Plenty else can be inferred from the contact network. As far as not listening, they have to be kidding if they think anyone takes that claim seriously.
