No, and in fact they have fought to unseal and publish the articles they have. The point is that if you read the subpoenas, they request a lot of data from Signal and Signal can only ever return the phone number, account creation date, and last connected timestamp. So either Signal is consistently lying to various governments or they actually don’t have any of that data. Signal’s client is also open-source and has been audited, and they have published many blogposts about how the technology works.
I’d strongly recommend digging deeper into this and trusting the auditors and experts instead of dismissing it based on lazy and cynical guesses. If you don’t trust anyone you’re welcome to read the source code of the client yourself. Soatok recently posted an 8-part series going through Signal’s encryption that you can read as a primer: https://soatok.blog/2025/02/18/reviewing-the-cryptography-used-by-signal/.
Since you’ve clearly not read or comprehended any of the subpoenas that I linked, nor the encryption analysis, nor read any of Signal’s blogposts, I see no point with responding any further. You are spreading FUD, and I question your motives.
