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
For the purposes of the average person the tech guy in your op is absolutely 100% correct.
All the platforms listed use transport encryption and that’s enough to avoid mitm surveillance which is enough for most people.
Most people’s “threat model” is the police or a pi. All the apps listed including signal have to comply with orders from American police and have “sidechain attacks” that involve stuff like getting some member of the groupchat’s device and scrolling up or tricking someone into giving up sensitive information.
Yeah, but when signal complies they give date you made your account and when you last accessed. And that’s it. Probably much less than the others give.
