A sponsor pays $10,000 to a content creator.
And then, they get zero views of their embedded ad in the video.
They got literally nothing for their $10,000 investment.
And let's say, for the sake of argument, that YouTube does not pay $10,000 for the same video, or ones like it.
Now, the content creator gets less money than they would have before.
It's almost like content creators have already done this calculus, and concluded that the best way to create content is to promote things.
It's funny to me when someone is like, "Why doesn't YouTube do X," and then they answer their own question, but then they still act like it's weird that YouTube doesn't do that thing.
