IE like Crypto AG:

In 2020, it was revealed that the Swiss company, Crypto AG, which provided secure communications services to ~120 governments throughout the 20th century, was secretly ran by the CIA and West German Intelligence. The CIA and later NSA were able to read encrypted communications for many countries such as Saudi Arabia, Iran, Italy, Indonesia, Iraq, Libya, Jordan and South Korea.

    All speculation. You gave them your phone number (which also means your real identity), so you should assume they have it. And because its a US-based company, it must adhere to US laws including key disclosure laws, which make it illegal for any signal employee to tell you that any US government has asked for this information.

    So the data that would be captured here is a network of hashed phone numbers and literally undecryptable messages

    With this data you can build social networking graphs: who is talking to who, and when.

    Also this is all the more suspect when you consider that US military / government agencies like OTF fund signal, and constantly try to push signal in privacy spaces.
