A flaw in this argument is quantifying this statement: "A significant portion of Google’s $27 Billion in revenue this year will come from their publisher ad network" The most recent data I was able to find is that AdSense brings in about 1/3 of Google's total REVENUE. And Google must pay publishers a substantial portion of this revenue which means it's nowhere near as profitable as the core Google.com property. http://www.123jump.com/earnings-calls/Google-Earnings-Call-Fourth-Quarter-2008/31158/ http://www.123jump.com/earnings-calls/Google-Earnings-Call-F...
