I understand, but its all about framing. “What does it Mean to be A Signal Competitor”, well that is chat apps as that is the space signal occupies. That might not be what space it occupies to you, but that is the space it occupies. “What does it take to compete with Signal’s Security” frames the argument to one component, and I would probably have a very different response to that framing. Because of the framing, your argument comes across as “don’t talk about use case, its not worth my time.” I understand this is because your focus is the cryptographic security, but threat modeling and Human factors has to be a consideration of an overall security posture. Congratulations, you have the best cryptography, but if its not usable, the cryptography doesn’t matter, if the users are the weakness, the cryptography doesn’t matter, if nobody is willing to use it because its missing a key user feature, the cryptography doesn’t matter.

I know enough about cryptography to know to leave it to the experts. I know about hardware power side channels, I know several exploits have been implementation based and not cryptography based, and I know vulnerability does not always mean an exploit
