I know for sure that drug trafficking and ransomware also exists on whatapp and facebook

There are some very big claims in that post. If half that stuff turns out to be true it might be the end for Telegram.

While some of the claims may be valid, this article is full of propaganda.

How can Telegram distribute messages in channels with more than tens of thousands users with P2P encryption? If there's 10k users, should Telegram store the same plain message 10k times simply because there's 10k public keys? If the sender encrypts and signs the message with 10k public keys, can the sender handle such a resource-hungry task? How can newly joined users decrypt old messages?

Of course there's fishy things, but the unprofessionalism severely drags down the value of this article.

I was in a commie-memes telegram chat that I think turned out to be literally Russian psy-ops. Pretty sketchy, that telegram, I've mostly stuck to Signal.

what kind of half ass country relies on Telegram for their military communication backbone?
