Ah thanks, okay, I'm not sure I'm missing anything in that case.
But if so, doesn't signal still know that alice and bob are communicating because it's transferring messages between them? Even if Bob doesn't log in IP B is still sending payloads that eventually get delivered to IP A, and if law enforcement later asks signal for logs they could be correlated.
Indeed, at some point in time a byte has to move from point A to point B, and unless you random VPN to a different location the source and destination IPs can be identified.
Even if they can't read it, a hostile government won't care.
There is only so much you can do against a really determined adversary thats well funded. I just want a Signal that doesn't tie everything back to a phone number.
