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

    Snapchat does not use end-to-end encryption for messages, so it doesn’t even belong in the conversation.

    WhatsApp and FB Messenger are somewhat defensible choices since they at least use E2EE by default (Messenger did not until recently). However, there are a few good reasons to favor Signal:

    1. It is open source. Interested parties can actually verify that Signal’s encryption claims are true. Interested parties can also audit new versions as they released.
    2. Facebook/Meta, as a company, has a long history of tracking users, leaking user data, and even conducting psychological experiments on users without consent and in secret.
    3. WhatsApp and Messenger only allow 6-digit PINs to secure your messages. With that PIN, you can decrypt those messages. Signal allows for longer alphanumeric passcodes.
    4. Facebook makes no promises not to track your usage of Messenger or WhatsApp, only that the messages themselves are encrypted.
