Found this post about "Google's Silent Monopoly"

I just came across this post about "Google's Silent Monopoly (Or How Much Does 
Google Pay For It's Own AdWords?)" on centraldesktop.com:

My initial thought is -- so what?  It's Google's product (AdWords) and they are 
free to do what ever they want with it.  If you are competing with Google of 
course they will place their OWN ads higher than yours -- it's a no brainer.  I 
don't feel we need to declare monopoly and take them to the cleaners for that.
