Even if MTProto is insecure I want someone I trust to tell me so.<p>it&#x27;s very likely insecure but the amount of negative press on the subject of telegram is worrying, would you rather people use whatsapp?<p>I know they&#x27;re not touting themselves as the bastion of security (like telegram does) but I&#x27;d rather people used telegram because at the very least the protocol is open source, and once they have federation and a released server it will be possible to improve on the security probably.
