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. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat. Telegram users are able to send files of any type up to 2GB each and access them from any device, with no limit on cloud storage, which has made downloading files more popular on the platform. Despite Telegram's origins, its approach to users' security has privacy advocates worried.
