Why is this article Facebook focused? Is this click-bait? Telegraph and iMessage also support unbreakable end to end encryption.
Also, if we're talking backdoors, why not just force Apple to unlock devices so that police can just read the messages in WhatsApp directly? That's something I could get behind as it means the intelligence community has to at least have the physical device on hand.
Do people have actual links to this treaty they're about to sign and what the exact wording is? I remember there being this 5-nation meeting in the summer with Canada and Australia that was specifically looking to lobby Facebook to open WhatsApp. Haven't seen anything new since.
