Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram boasts 500 million users, who share information individually and in groups in relative security. But Telegram's use as a one-way broadcast channel — which followers can join but not reply to — means content from inauthentic accounts can easily reach large, captive and eager audiences. "He has kind of an old-school cyber-libertarian world view where technology is there to set you free," Maréchal said.
