I don’t see how this “clears” Waltz.<p>For one thing, as far as I know, the iphone doesn’t attach phone numbers to contacts automatically, it just asks. The article claims the iphone did it, but I think Waltz must have.<p>Also, this why you don’t use a random group chat app for national security conversations. Your general app is designed for engagement which includes building out the social network. Of course it’s going to err on the side of inclusion, when here you want to err on the side of exclusion.<p>For national security, contact info would be vetted, verified, and strictly up-to-date. There would be multiple guards that would prevent a thoughtless tap months earlier from leading to the wrong person being given national security information.<p>It sure is frightening that these bozos are in charge of things that have high stakes.
