As someone who is outside of the security research community, the repeated assertion that "telegram is broken" is rather hard to accept without an example exploit. I would really appreciate if someone with the knowledge of how to break something like this took the time they would spend writing a blog post about it being broken and instead demonstrated an attack.

Having relatively low security requirements (I simply don't want to see ads based on my conversations), I'll continue using it to talk with my friends and family until someone demonstrates an exploit.
