Unfortunately, I don't think the 'Nobody is going to die' statement holds up for software like cryptocat. If it is promoted as secure, then it could be used in areas with hostile regimes. For example, members of the Arab Spring uprising might have trusted cryptocat, but what if their governments were intercepting and decrypting those messages due to a flaw in the software?

Bottom line, explaining away problems by saying 'nobody is going to die' is a downright dangerous statement IMO.
