Lol, privacy is definetely not what you’re getting with Signal. They know your entire connection graph, who you talk to, when and how much. They collect all of the phone numbers.
EDIT: It seems like people here don’t understand what privacy is. If I know when exactly you take a big shit on the toilet and where you do it, every single time, but I don’t know what it looks like when you are doing it, would that be a privacy concern for you?
