Yeah, I don't see why people have a hard time with a platform trying to support itself. Video hosting is expensive and there is a reason why there are few competitors that allow such open upload limits that is easy for anyone to use. Right now it is a good price for what it gives since YouTube Music is somewhat decent.
A decent share of the Premium cost goes towards actual channels that you watch, if more people had the attitude to pay for the service, we would probably see less ad integration for a lot of creators and they could actually be paid from the Premium subscribers
