Most people think about their own protections when they sign/encrypt their email, what people don’t consider is the privacy and protection of their friends and family. If your mail is intercepted or someone spoofs your address to send an email to your friends, your lack of signed/encrypted email puts you both at risk.
Falkvinge made a clear case for why all collected personal data will be used against citizens. However, what’s more is that the data that cannot be obtained through collection can be manufactured unless you take the proper precautions to protect yourself and your friends.
Let’s create a hypothetical senario: Your friends and you like to dance, and your fancy is tickled with some modern alternative dance to the beat of some new aged music. You feel the music in your soul and you just let your body flail like a bat fighting a chupacabra.
Every week, you and your friends send each other emails about where you want to meet up and shake your groove thing. It’s all fun and you guys stay out of trouble. There seems that nothing could go wrong in this picture. Except elections are coming up soon and let’s say hypothetically some fundamentalist religious dude is elected to the shock of everyone.
When this man takes over office, one of his smaller directives which get’s passed over by the media is to end this new heathan dancing (which would not be unheard of ). As you are the hub of your friends who keeps everyone in contact, these agents who are charged with “protecting culture” spoof your email address and send out emails to all the other members in your little dance movement and have them meet you at a location.
Since you don’t sign or encrypt your emails, everything you send out is basically a post card. These culture warriors were able to study your writing style, and who you send your emails to. They were able to round up all the members of your non-violent fully legal gathering because YOU were too lazy to setup GPG encryption.
Maybe you hate dancing though, maybe you don’t see yourself as a member of any counter culture movement and are a normal guy on the street. You have no need to protect your speech, eh?
What about email conversations that have your personal medical information? Would you write a post card to a friend that details a rash or other condition? No, it’s something that is private. It’s private for a reason, and you should respect your own privacy enough to encrypt that email.
Emails are post cards, when you don’t encrypt (or at the very least sign) your emails with GPG… you are putting yourself and the people around you in danger of at the very least an embarracing situation. Let’s face it, the reason you are not using GPG is because you’re lazy… so is it worth it?
