Mark Zuckerberg on Instagram: "WhatsApp is far more private and secure than iMessage, with end-to-end encryption that works across both iPhones and Android, including group chats. With WhatsApp you can also set all new chats to disappear with the tap of a button. And last year we introduced end-to-end encrypted backups too. All of which iMessage still doesn't have." | Zootzle
