Whenever I open Youtube via an EU proxy, I see "a crypto scam" video at the front page, the first one. The title is "+35 ETH generated last month by effectively using the contract bot for trading" and the account name is "Web3 developer", and the label says "Sponsored". The thumbnail displays a happy bearded man's face resembling that famous Youtuber who gives away money, a fire emoji and words "+35 ETH in July personal bot".
So you cannot really blame Telegram.
