Re: Not a moment too soon
People also do legitimate business over the internet. That requires that it should be possible to exchange information confidentially if that's required and essential to confirm a transaction reliably. By "reliably" I mean that it shouldn't be possible for some third person to intercept and amend the transaction, impersonate one of the parties, forge a transaction nor for one of the parties to repudiate their part in it. That requires an end-to-end secure system. Whilst that may upset some branches of government others, those concerned with trade and the economy, should be pressing for it.
While personally I'd not want to use anything provided by Facebook for such a purpose the need for a secure, end-to-end secure messaging system needs to be met somehow and the best way to achieve it would be through an open standard defined, in the internet way, by an RFC with multiple, including FOSS, implementations available. Email ought to provide that but doesn't, not without add-ons. Either e replacement standard is required for that or a new standard is needed to sit beside it to provide for such messaging.
