But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat.

So, uh, whenever I hear about Telegram, it’s always in relation to something bad. What gives? 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.
