> I as a Signal user want to communicate securely with Facebook Messenger users. Therefore Facebook must allow me to reverse engineer their services and make unauthorized systems to allow me to create a service to send messages to Messenger users from Signal.
That's precisely what Signal started out as :)
Before Signal existed, it was common to use Pidgin or Adium with OTR to send encrypted messages through SMS, Google Chat or Facebook Messenger.
TextSecure – the original name of Signal – was created to improve upon OTR by allowing it to better handle situations where one user was offline while the other tried to send messages. Originally it only supported sending messages via SMS, not via their own servers.
