The Russian invasion of Ukraine has been a driving force in markets for the past few weeks. One thing that Telegram now offers to all users is the ability to “disappear” messages or set remote deletion deadlines. That enables users to have much more control over how long people can access what you’re sending them. Given that Russian law enforcement officials are reportedly (via Insider) stopping people in the street and demanding to read their text messages, this could be vital to protect individuals from reprisals. Groups are also not fully encrypted, end-to-end. This includes private groups. Private groups cannot be seen by other Telegram users, but Telegram itself can see the groups and all of the communications that you have in them. All of the same risks and warnings about channels can be applied to groups. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion.
