Your supposition is misguided. When a person creates a product, they know what their monetization model is. YouTube creators included. They know their money comes from ads, via views. This suggestion of handing out money to them is misplaced. If your friend opens a shop and knows their monetization model is sales, are you implying if you want to support them you are just going to hand out cash to them?
Me watching their video with the ads open up a whole lot of other revenue opportunities to them as opposed to just handing them out money. They are not a charity case.
