Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Recently, Durav wrote on his Telegram channel that users' right to privacy, in light of the war in Ukraine, is "sacred, now more than ever." Unlike Silicon Valley giants such as Facebook and Twitter, which run very public anti-disinformation programs, Brooking said: "Telegram is famously lax or absent in its content moderation policy."
