Re: Your deleted The fact that in Signal's case, the client and the server are fully aware of who each other are is immaterial (thus not part of the analogy). What the analogy demonstrates is that there exists a potentially-retaliatory party that sees the server identify itself as someone else. That someone else (in this case, the cloud provider) has the right to protest the use of their identity in a way that makes it a target for the retaliatory party. Have a great day.
