My understanding of the GFDL is that it means you could even stand on a street corner and sell bound copies of its content for a fee. Someone will undoubtedly correct me if this is wrong. Free as in speech, not free as in beer.
Thanks for the information. So I guess it is not a copyright issue but it does raise questions about misuse of Google Adsense and Wikipedia content.
On a hunch, I decided to do a search for a phrase from a random Wikipedia article. I searched for the phrase "new AC alternator on all Fords and the now-famous Mustang GT" on Google. http://www.google.com/search?q=%22new+AC+alternator+on+all+Fords+and+the+now... or http://tinyurl.com/67j67
I got 19 hits. Out of them, 12 display Google AdSense links. I did not realize that so many sites are using Wikipedia content to collect Google AdSense revenue.
