Youtube is a carrier, rather like UHF frequency is a band for transmitting carriers. Your television can show anything, depending on which channels you choose to watch. YouTube service also contains just about anything, and there's no such thing as a "YouTube front page" like you have front page of a newspaper. It's your own front page that comes up, based on what you've previously been interested in.
If you are interested in fake news, you'll see fake news in YouTube. Just like if you're interested in supermarket tabloid stories, you'll buy National Enquirer and read that. It's your choice.
