I don’t understand why Telegram is so popular. It is not encrypted unless you enable secret chats. Signal would be a better option (even with the metadata leakage).

As of right now SimpleX is probably the best option (unless you have a group chat with more than a few hundred people). Thankfully they are working on performance fixes to help large group chats that will land later this year.

Man, I thought you were talking about this kind of backdoor bug!
