This telco is claiming that they have the technical means to prevent that - while in fact they have no technical difference (other than storing your email encrypted) than any other. That isn't my interpretation. They seem to be saying that they will do everything technically and legally possible to prevent tracking. That's a significant difference from the current situation where telcos hand over information whenever the government asks, even if not ordered to do so.
