I think that's precisely his point; even if Vogue has an ad network with highly accurate data that points you being interested in SSDs, Vogue is probably not the right place to put that ad. It's kind of a philosophical question - do you want to see ads that are relevant to your primary interests at ALL TIMES, or do you want to see ads that are relevant to the interests of where you are. There are, let's simplistically say, three classes of ads:

1. Old Internet - Pages curate and/or sell whatever ads they can possibly get. They are generally statically hosted assets. 2. Original Ad Networks - They don't know anything about you, but it removes the need for pages to individually make ad contracts. You'll get whatever ads are in the queue, possibly sorted by rough groupings; "technology" ads, etc. 3. Current Situation - Everywhere you go you are presented with ads relevant to your interests, regardless of your current site. Vogue might try to show SSD ads or car parts ads, even though that's not the kind of content you would go to Vogue to consume.

I think there's an interesting case to be made that clickthrough decreases can be at least partially attributed to the fact that as tracking increases the probability that the ad represents the content of the site decreases and becomes an even more unwelcome distraction. Sponsored content is a way to defeat this, and ad blocking, by making the advertising appear more in line with the content of the site (or is it making the content of the site more in line with the advertising?).
