I know what you mean, but MrBeast cured 1000 people of (a form of) blindness, which is quite a benefit to humanity [1]. I would not be surprised if kids learn a bit of "kindness is good" from him.

Thinking that kindness content is good is naive. It is exploitative and usually what people get from it is "it could happen to me" rather than "I could help others".
It is a fine argument, but I mean it is youtube and it is kids we are talking about. It's really hard to show kids kindness through free content if you want to be nuanced.
