Unpleasant news for all WhatsApp users. Since the beginning of 2019 the popular messenger will lose the function of end-to-end encryption of user correspondence.It is reported that this decision was not caused by a whim of the developers. According to Mark Zuckerberg, the founder of Facebook, which now owns WhatsApp, such measures were demanded by the United States authorities. The refusal to encrypt user messages should help intelligence agencies to identify potential terrorists and people with mental disabilities by gaining access to their correspondence in the messenger. As Zuckerberg noted, these measures will help both the United States and Europe and other regions of the world to ensure the safety of their citizens, as police and intelligence agencies will be able to identify lawbreakers more quickly and prevent terrorist activities.
