Little does he know but he is just making encryption even more popular....
Try surespot instead of whatsapp. It's open source and does end to end encryption rather than server side. It is not tied to your phone or email, It allows you to delete your content on your device and the devices you sent to. A+
Also have a look at Wickr, offers end to end encryption with auto destructing messages and also not tied to your phone, name etc... and also offers a desktop version which automatically syncs with your mobile so easy to jump from the one to the other.
