Excellent! 3 questions:

- What if the government forces WhatsApp to write and push a targeted software update in order to compromise the end-to-end encryption (I'm of course thinking of the FBI vs Apple case)? Is there a way for the user to be notified?

- Does WhatsApp Auto Backup encrypt messages before sending them to Google Drive or iCloud?

- Would it be possible for WhatsApp Web to rely on backend servers storing an encrypted version of messages, instead of relying on a connection to the user's phone, and still be able to perform keyword search over the encrypted messages with something like github.com/strikeout/mylar?
