Developers rage after Facebook blocks Google AdSense - Yahoo! News
Well well well, the knives are coming out. Facebook appears to be blocking Google AdSense and Amazon ads on their website. Facebook is requiring any advertisers to sign a restrictive agreement preventing them from using any Facebook data. It would seem unlikely either big company would agree.
Better be careful kicking dirt at the biggest kids on the block. They may build a more open version of your website. :)
