Telegram was never properly end-to-end encrypted. The way this works is Telegram client sends stuff to the server over client-server encryption. The service provider stores it on server's disk in Netherlands. Since Netherlands is not US, to NSA's hacking team Tailored Access Operations, hacking the server is considered 'fair game', i.e. there are no restrictions. When they hack the server they can read the life of 900,000,000 telegram users. It's that simple.
You shilling for Telegram's tech-billionare who got caught for hosting child porn for closer to a decade is almost as sad as Telegram's sad state and Durov's future.

I have now come to realize (based on [1]) that Telegram's platform was not secure by default, nullifying my arguments here. This discussion has also led me to question the viability of one of my own projects, as it, too, encrypts at disadvantageous points in the pipeline. Hmmm. Sorry for my mistakes here!
