I was abroad this week when Brazilian court has ordered mobile operators in the country to block WhatsApp for 72 hours due to a dispute over access to encrypted data (the decision was reversed and service restored a day later). WhatsApp refused to turn over chat records related to a drug investigation to the courts, claiming these records are not accessible following the newly implemented end-to-end encryption capabilities.
The most popular messaging app that people use is WhatsApp, with more than more than 700 million active monthly users worldwide. Acquired by Facebook in February 2014 for $19 billion, WhatsApp has recently added free voice calling to its service. With this strategic move, the company is going aggressively after competitors such as Skype and Apple’s FaceTime that are also providing OTT (Over-The-Top) applications.
