After fleeing Russia, the brothers founded Telegram as a way to communicate outside the Kremlin's orbit. They now run it from Dubai, and Pavel Durov says it has more than 500 million monthly active users. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea.
