Unless signal demonstrates they can't link usernames to phone numbers, I call BS.
Privacy by policy is great, but it's not zero knowledge. Since they designed the system to ultimately identify people to phone numbers there will always be the potential they are logging all the username phone numbers hash lookup tables
It`s good to always be sceptic, however I have been using and following Signal for years and so far they have not given me a reason to misstrust them. You should read their answers when some judge with 0 digital competence tries to subpoena some chat protocol.
The article states that they are only saving a hashed copy of the currently set username, if any. While they might in theory keep more than that on hand, their policy has always been to minimize accessible data, and have responded in kind whenever subpoenaed, which is at least a very strong evidence.
The code is also fully open source for both server and client, so you could independently validate it yourself.
Are you sure code for server is open source? I thought only the client was.
