Link to article from main Lemmy❤️ developer about Signal privacy. Mostly fair points. I kinda distrust so centralized services but basically we have no other options (Matrix is buggy in many aspects). What can you say about this article?
The EU commission who are actually targets of nation states recommend to switch to signal. Also it was tested in court and the data wasn't there to give.
If you are a target they will go for the weakest link either hack the device or they will go for the other participants device to get the conversation there. They don't need to break the encryption.
