The strong encryption with iMessage only works if you're communicating with someone else who's also using iMessage. Apple has to control both ends of the conversation to ensure security. Remember, iMessage is built into the Messages app in iOS, so when you send a text to someone who is using iOS or OS X, you'll get security. If you use Messages to send a text to someone using another operating system (Android, Windows, etc.), there is no security. The same problem arises with email. You can only send encrypted email to someone who has taken the trouble to share a public key with you. I make my public keys readily available, but there are few people who use them to encrypt email to me. Unencrypted email is just like sending all your snail mail on postcards. Encrypted mail is like sending your snail mail in an envelope nobody but the intended recipient can open. I've been encouraging people to use encrypted email for many years, but it seems most people just don’t care who sees their email.
