It's not really the same ad revenue. Sponsorships are completely different campaigns and budgets from typical programmatic video or companion ads run on Youtube. As far as YT is concerned, their ads pay for the hosting and delivery of the content, but it's the creators who actually create the content and they can include whatever they want (as long as its legal, etc) with their audience deciding if they want to deal with it or not.
