David was likely approaching the subject from the standpoint of a user -- no one likes ads that are too in-your-face and irrelevant. But as a Division Head (no longer CEO...), he has to ensure that he is profitable. Like I said, I don't know how good Yahoo's ad-serving network is, and hopefully they have a broad & deep enough pool of content to show visitors, so that Tumblr remains a viable publishing platform. Given Marissa's previous stint at Google, I expect her to focus her attention next on their ad-serving. A large & strong revenue stream will keep the board off her back and give her time to fix other things there that need fixing.
