Is Telegram really an encrypted messaging app?

This is a most excellent place for technology news and articles.
MTProto 2 has not been cracked. MTProto 1 had a weakness and Telegram addressed it. That was many years ago. I'm not aware that MTProto 2 has ever been cracked in all these years. Telegram's unwillingness to cooperate with governments is an additional security layer.
In my OP, I was merely referring to how FB Messenger and Telegram functions the same.
Speaking to the protocol used for encryption is a moot point… because even if MTProto 2 was better, it’s still not enabled by default in both messengers.
