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

Signal is the only app on that list whose app is open source. That means it can be audited to see if they are telling the truth.

You cannot say the same for the others and you just have to take them at their word. Should we take Facebook at their word?

It's also the only app on the list managed by a 501(c)3 non-profit, so you can additionally check where their money goes.

That's true! I can't wait to "shoot" back with arguments :-)

Also the FBI took signal to court and the only data they could provide was the date of signup and last login timestamp

This is an important extra point: being open source, a government can’t secretly mandate a back door, because everyone would be able to see it. For the other options listed, there are no guarantees.

They can put the backdoor in themselves though, see the recent xz backdoor. But the question is whether it would be found out or not.

xz backdoor rely on two testfile with malware, some script that do specific thing to malware to unmask and inject. If commit later change any part to break backdoor, signal probably forced to reject to keep backdoor.

But why reject good change? Might raise red flag.

xz almost worked because it was in something nobody was looking at. Signal code is audited regularly.
