Nobody is objecting to a feature that deletes certain messages after a
configurable time. I agree that it mitigates some attacks (although less than
one might think, if the mail account isn't tamper-evident), and timed message
deletion has other benefits besides. Many MUAs provide this feature, often
through "filters" or "rules" interfaces.

Rich's objection, which I share, is that Wickr (and apparently, Silent Circle)
attempt to impose this policy on users without allowing them to make an
independent choice.

Is your position that timed message deletion is valuable only if it is
sender-selected and MUA-enforced?
