The point of ads isn't always to get a reaction. Clicks are the grand goal of course but mere impressions are valued by marketing standards as well. The fact that the target audience sees the ad, even if only passing by while scrolling is widely considered a success by marketing standards. And equally needless to say but I'll say it anyway; that's the very point of Zuck leeching, so the ads will find the target audience.

Agree with you there that this isn't much of a privacy leak as the average user mostly knows what's going on. I'd guess the article wasn't really meant to point out a threat to privacy, maybe more on the lines of "FB doesn't want to share it's methods of using the information it gathers". Shocking...
