As Russia launches criminal probe against Telegram CEO, the app's critics come to its defence

Pavel Durov, the billionaire CEO of the messaging app Telegram, has confirmed Russian state media reports that the country's Federal Security Service is investigating him for "aiding terrorism." Access Now - a digital rights non-profit that has been vocally critical of Telegram's security and privacy in the past - says this probe is nothing more than a pretext to crack down on free speech.
