> At the end of the day, advertisers and viewers can't possibly care what video it's showing on as long as they're getting the right target audience.

This isn't true?

Advertisers certainly do care. They don't want their ad dollars to be spent paying publishers for content that's controversial because it makes them look bad. It also has the potential to damage their brand.

This actually happened and is what led YouTube to lose a significant amount of ad revenue which in turn created the situation we have now.
