Encryption App ‘Signal’ Fights Censorship With a Clever Workaround
Andy Greenberg on Wired:
“Now when people in Egypt or the United Arab Emirates send a Signal message, it’ll look identical to something like a Google search,” Marlinspike says. “The idea is that using Signal will look like using Google; if you want to block Signal you’ll have to block Google.”
Smart. Since Signal is not as widely used as WhatsApp, blocking it doesn’t cause same uproar. This workaround ties its fate with Google, which is like using Godzilla for your canary in a coal mine test.
