For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov. "And that set off kind of a battle royale for control of the platform that Durov eventually lost," said Nathalie Maréchal of the Washington advocacy group Ranking Digital Rights.
