“WhatsApp killed the operation,” the official said. Yeah, they detected anomalous activity, investigated, and alerted affected users. This sounds like a point in favor of WhatsApp and Facebook, looking out for the integrity of the apps of their users -- but it still won't convince me to stop using Wire and Signal and adopt WhatsApp. Curious: does any version of this story say what model of phone the terrorist suspect was using? If it was an Android then quietly asking Google for tracking info on the phone should have been easy; if it was an iPhone this would be quite newsworthy since Apple asserts their phones are secure from attack and Apple as a whole have made a very big deal about privacy of user data, something which I think would be appealing to a terrorist trying to communicate covertly.
