@maxigaz I suppose when talking about these things the best way is never ever using the word "privacy". Actually I read somewhere a very bright article about this topic (never using the word "privacy"), but I just cannot find it anymore. There are expressions like data protection or protecting messages, etc. which sound better and don't annoy people (because using "privacy" sounds like someone is some kind of a criminal or brainless paranoid, like in that movie Conspiracy Theorie).
