China has largely blocked the WhatsApp messaging app, the latest move by Beijing to step up surveillance ahead of a big Communist Party gathering next month.

The disabling in mainland China of the Facebook-owned app is a setback for the social media giant, whose chief executive, Mark Zuckerberg, has been pushing to re-enter the Chinese market, and has been studying the Chinese language intensively. WhatsApp was the last of Facebook products to still be available in mainland China; the company's main social media service has been blocked in China since 2009, and its Instagram image-sharing app is also unavailable.

WhatsApp uses end-to-end encryption, which the Chinese government (and western governments) don't like. Either WhatsApp would give China a backdoor, or China would block WhatsApp. This seems to indicate WhatsApp stuck to its encryption.

Let's see what happens to the other big western messaging service with end-to-end encryption still available in China: iMessage. We can safely assume that if iMessage isn't blocked soon, Apple caved, and gave China its backdoor.

Apple doesn't need to physically backdoor iPhones to decrypt iMessages. The certificates for all devices are fetched from their servers. All they need to do is introduce a rogue cert and suddenly you're sending messages to additional recepient without even knowing.
