Actually good vs. bad advertising is tricky. When ads are very targeted and try to show you things the system thinks you are looking for, you get a small number of relevant ads vs. a bunch of spam ads. In that sense, they are actually very good and can be useful for some people. Sometimes, they can even help you discover things you couldn't find through a direct search. On the other hand, the data collection and analysis you have to do in order to target effectively seems bad to most people. I'd rather have my privacy and control of my own data than get targeted ads, but most people don't seem to have the same awareness or concern. In any event, that quote isn't quite accurate. Behaviorally targeted ads are the result of data obtained from people actively searching for something or browsing as well. (Behavioral targeting is really where the money in in FBX). They may be showing you something you don't know you want, but more often, they are showing you what the system thinks you were looking for but couldn't find.
