There are no ads at all provided by YouTube. Obviously Google can't prevent content creators from embedding their own ads, which is becoming increasingly common.

Of course they could, just make it part of the service agreement.
I would feel much inclined to pay for youtube if they filtered out all ad-funded content.
Even better, they could have a model where content creators for the paid service got their piece of the revenue based in quality metrics rather than quantity metrics.
