related from telegram author: https://t.me/durovschat/515221 https://t.me/durovschat/515221 (most his stuff is posted in telegram) He is saying telegram clients are open-source AND verifiable so you can prove the app store is giving the pushed source. And there is no point of open-sourcing the server because it doesn't allow you to prove more about the encryption and you can't prove the published source matches reality. Obviously there are business/brand reasons as well, but I think Telegram is being honest here.
