(I haven't watched his videos; I only know about MrBeast from this article and passing conversations.) I think the moral discomfort that's being identified here is a reasonable one, and stems from the same basic (and intuitive) source as the familiar "billionaire philanthropist" thought experiment: many people have a strong intuition that publicized philanthropy is in some ways less praiseworthy than the contents of its actions would otherwise imply. That source, in turn, is something like our recognition of other self-legislating agents: we know that the actions taken by others are done with independent ends in mind, and it's reasonable to think less of an action when we have a good reason to believe that the person's ends are not themselves free from inclination (desire for praise, fame, etc.). In other words: people like MrBeast intuitively inspire distrust and "ick" reactions because they give the the impression that the observer is being had in some way.
