Hey Folks! Someone in my family (Person A), has talked to a guy, who is working in the tech world, about if it make sense to use Signal, over Messenger, Snap, WhatsApp, with privacy in mind. The tech guy said, there is no difference, and that its not making sense to use it and that its almost the same. I know Signal is discussed alot here, but im now looking for some arguments, and facts to tell the one from my family, that the tech guy is wrong. What arguments can i use, why is Signal better in privacy, then the other alternatives? Person A, has always been sceptical about me beeing so privacy minded, and A thinks that there is nothing to do to protect, and is one of thoese saying : I have nothing to hide.
Edit: thank you for the help
Whats’ app, while E2EE can still pull lots of information from who you message, how often, the size of the messages, and contact’s phone number. Messenger has the content of your messages and with whom you converse according to Facebook account info stored on Facebook servers. Snapchat has a record of all activity, contacts, and message content. The messages only disappear from app but not from SnapChat servers. All 3 of those record of how you live your life, except Whatsapp can’t see content of messages but still has your activities and contact phone numbers.
Signal was ordered to turn over user content to court and Signal only had when the user last connected to the service and date of account creation. Signal had zero information about messages, when messages were sent, or to whom.
