No, that napkin math doesn't check out unless you think Youtube is a non-profit. They pocket half of what creators make, and that has no relationship to their infrastructure cost, it's a function of their market power. They could change that revenue split tomorrow to 70/30 while they cut infrastructure costs for all you or I know.

You somehow turned my argument on its head. I don't care how much Netflix or YT pay for content, I only care that I pay directly for content, and because Netflix is a media company, not a platform, I don't need to guess how much they're squeezing creators or consumers. I transparently pay for a movie catalog, and that is the service provided.
