Interesting... and unfair situation.
I wouldn't like to be on the skin of people who pay for advertisement, as said in the article, those are the ones who are most decieved. They put their money in, and don't get what they deserve.
But it's also bad for consumers, instead of getting the stuff that would really be of interest to them, they might get a lower quality google product, only because google is the one hosting the advertising.
On the other hand... This is what we get for allowing google to get this humongous empire.
Honestly, i like google for its fantastic search results, and for taking out a big part of those intrusive ads we used to see. This doesn't mean i don't understand the people who pay for advertisement, it only means i prefer it like this than the old times.
Yes... Call me selfish..
