The Telegram messenger application was banned across the entire territory of the Russian Federation, following a ruling by the Tagansky district court in Moscow on Friday. The hearing was held after the Roskomnadzor (Russia's Federal Service for Supervision of Communications, Information Technology and Mass Media) appealed to the court to block Telegram following the company's refusal to give... Еще the Federal Security Service (FSB) access to the users' messaging data. Telegram's representatives had announced earlier that they did not plan to follow the order of the regulator to provide the FSB with encryption keys needed to access the data. The company's lawyers and representatives boycotted the hearing, advised by its founder, entrepreneur Pavel Durov. With its 15 million users, Telegram is one of the most popular messaging applications in Russia.
