OWS's staunch refusal to permit anything other than phone numbers as identifiers should tell you everything you need to know about Signal. It is an authenticated, nonrepudiable communications platform using identifiers that are very difficult (possible, yes, but most people will get it wrong) to comprehensively anonymize. The ability to present nonrepudiable communications to a judge is precisely the wet dream of law enforcement officers, ambitious prosecutors, and despotic regimes everywhere. All they need to do is flip the people you're communicating with, and you're done.
