Signal does not know who talks to whom. It's kind of the main thing about the double ratchet.
Unless you compiled the app yourself from source code that you understand, you don’t really know what the app might be saying to Signal’s servers. Almost everyone just trusts that the pre-compiled app supplied by Apple or Google aren’t compromised. But we know from history that Big Tech and the military-intelligence-industrial complex are in bed with each other.
Okay. You tell me what the double ratchet is, since you're so smart.
The double ratchet algo is irrelevant if the app is doing something else altogether.
Compiling the app is irrelevant if I don't read the source.
That's nonsense, because many different people read the source and audit open source software. While it's certainly possible to sneak malicious code in, the trust doesn't depend on each single individual auditing it. It's a collective effort.
