I don't think that's true. They're probably referring to the people who fall down into alt-right/whatever radical group "rabbit holes." These people aren't radical from the outset. I'd say the real issue is the youtube algorithm, which causes the radicalization "highway" in the first place, but apparently youtube can't be bothered to fix their harmful algorithm, and would rather delete the content that is being promoted by it.
I guess you are not a humanist. Your perspective is that people are easily manipulated and need to be told by other people whom are easily manipulated how they should think.
