As said in another comment, I am no cryptography expert. I simply argue against the very visible negative bias against Telegram which is accentuated even more by very childish snarks on almost any Telegram HN thread. That gets to me and it's not how HN should be.

I never argued that my opinion is a fact. I said how I arrived at my opinion and debate with people whether that's plausible or not [based on limited info]. The rest can be proven/rebuked by specialists.
