Hm, this was a few weeks ago. I just thought it was ridiculous that a creator would put an ad every three minutes on a three hour video. I guess it's possible.

There were some other creators that I saw some less egregious but still questionable cadences with, which I thought would go against their general ethos (like ads every five minutes on an hour long video by a person who is generally against a culture of over-capitalization).

Maybe A/B tests?
