Such efforts apparently don't fly with the Russian authorities, as they threatened to ban the app there if the company doesn't give them access to encrypted communication, and then followed through. They didn't end at it, though, as both the App Store, and APK Mirror, have reportedly received requests to block the app for users, presumably in the home turf. Telegram is appealing the ban in court, but, you know, it's like appealing an NSA request to hand over data on national security grounds, and might be an exercise in futility.
Russian law requires that authorities have access to the encryption keys of such secured communication services, and Telegram, as originating from Russia, might fall under particular scrutiny in that regard, though there are plenty of other encrypted chat messengers that can be used instead. The kicker is, however, that VPN usage can circumvent such bans, so the Russian digital media watchdog banned almost 2 million Amazon and Google IP address that were used to run Telegram around the block, resulting in messed up business operations for other services using them.
So, Telegram is officially banned in Russia now. To enforce this ban our government blocked over 2 million ip addresses today, mainly from Amazon AWS and Google subnets.— Rannor Medved (@rannor_ru) 16 април 2018 г.
What a time to be alive.
