I think you missed the point. Google bought youtube because for them bandwidth and storage are cheap (it's CPU that is expensive).
Back in the 90's when bandwidth was expensive we managed to run a free video site without advertising. Since then bandwidth has become orders of magnitude cheaper, and G has economies of scale that no other operator can get close to, they quite literally own the fiber, the endpoints and are present in just about every meet-me room all over the world. Storage costs have dropped even further. So what you think costs Google a couple of bucks to provide per user probably costs them fractions of a cent. And if they dropped the garbage their costs would be even lower.
Considerably less than that. So much so that our 1 Gbps uplink was enough for a few thousand streams. But so much more expensive and with such lousy compression ratio that you could to much better today for less. Apples to apples.
