I think the only reasons why people hate YouTubers for making money is because they are full of jealousy because you would be the one making the funds, and they would think you're only doing it for the money. But I would think that if they were truly loyal fans, they wouldn't care about how much you're making and they would be happy that you; the video creator, care about your fans. Fans would see right away if you were just doing it for the money though

So they could also be scared that you became greedy. That could be another reason why they rage.
