I would like to hear opinions on the value of deniability in OTR like

>From a privacy perspective the rationale is fairly clear. But I keep
reading stories like this one:


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.
