I need more specifics on the UK’s planned ‘ghost protocol’ otherwise known as Eve or Mallory in the Alice and Bob cast of characters. What messenger apps will be affected by this? Because if I was building a messenger app I would pull a Lavabit and disband it if coerced to put in back doors. Heard great things about Matrix/Element app. Is such an app impervious to back doors though? I mean the protocol is open source right? How do you back door something open source? WhatsApp can be considered to be unsafe to use, that I know, but what about alternatives like Cwtch, and things like Session?
