I would like to hear opinions on the value of deniability in OTR like protocols.
>From a privacy perspective the rationale is fairly clear. But I keep reading stories like this one: http://www.dailymail.co.uk/news/article-2854324/The-double-life-tragic-suicide-girl-accused-rape-tycoon-s-son-says-Don-t-judge-know-story.html in which people exonerate themselves or get themselves out of a sticky situation because they are able to prove someone sent them text messages at a certain time. E.g for establishing an alibi or (as in this case) to show that a woman who had accused a man of rape was lying. If you have true end to end encryption and only you or the sender can release messages, this seems like a pretty high standard of privacy already. I'm not entirely sure I'd actually want to use a system that added deniability on top, because being able to prove a conversation took place is so often valuable in life and in business.
