I disagree. It is still quite trivial to reasonably exchange information without anyone being able to eavesdrop on it. Authenticity isn't important if the message content can be verified. It can even pose a danger. People like to attack the messenger, especially if he has a point. Don't know about your devices, but mine do not put me under surveillance. Smartphones are critical, but even those are controllable. If you are in public you won't know, but otherwise you can be reasonably safe.
