Friend does not believe in encryption & privacy
I have a friend that everytime he hears about encryption and privacy, laughs and says something like “you are naive if you think companies don’t have backdoors to read encrypted messages in case the government needs to”. He is referring to signal, whatsapp, proton, ente (everything with e2ee).
He is in the army. I never know how to give an argument. Can someone give me ideas on how to discuss this encryption subject with someone like him?
