Think your emails are private? Think again

In Andy Yen's ted talk, "Think Your Emails are Private? Think Again" he explains that when people send emails to each other, it is not a private conversation.  Instead, corporations and government officials are able to see each message being sent.  With that said, most people would feel uncomfortable with other people reading their private conversations, so Yen has establish a way to entirely have a private conversation via emails by developing a website called ProtonMail that sends encrypt messages.  In my opinion, I had some idea that emails sent to each other were not private.  In the past, I learned that government official are able to look at your message.  I saw a video where a man was immediately arrested and taken to the police station for questioning after he posted something on Facebook concerning the president.  To me, I would feel very uncomfortable with other people reading my messages just because I want it to be private.  But what can you do?  You have to follow the rules and regulations and agree to whatever you are doing before creating an account, so ProtonMail might not be so bad to try out.
