In February 2014, the Ukrainian people ousted pro-Russian president Viktor Yanukovych, prompting Russia to invade and annex the Crimean peninsula. By the start of April, Pavel Durov had given his notice, with TechCrunch saying at the time that the CEO had resisted pressure to suppress pages criticizing the Russian government. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. These entities are reportedly operating nine Telegram channels with more than five million subscribers to whom they were making recommendations on selected listed scrips. Such recommendations induced the investors to deal in the said scrips, thereby creating artificial volume and price rise. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
