"There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram users are able to send files of any type up to 2GB each and access them from any device, with no limit on cloud storage, which has made downloading files more popular on the platform. Despite Telegram's origins, its approach to users' security has privacy advocates worried. In the United States, Telegram's lower public profile has helped it mostly avoid high level scrutiny from Congress, but it has not gone unnoticed.
