It started out with so much promise: Google Allo, a new messaging app that would take on Apple’s dominance. And it even came with end-to-end encryption — but there was a catch. You had to turn on the encryption first which, in an age of paranoia, wasn’t enough. That drew ire from privacy experts and security researchers alike — even Edward Snowden took a swipe at it. He called the app “dangerous” and “unsafe,” and advised users not to use the app until the default encryption issue was fixed. What did Google do to fix the problem? Nothing. It reversed its position entirely and began storing messages indefinitely — for every intelligence agency to see.
