Isn't it likely that Google charges the advertisers for each time an ad is shown? So lower view counts mean lower ad views which means lower revenues for both Google and the content creators. (And, if the advertisers are counting on the views to drive their own business, it could mean lower revenues for them to go with the smaller ad bills.)

The ads are not shown anyway. This is about the video where the ad would be embedded. Those are two different view counts.
