Declan McCullagh has the story of the surprising entry of Big Corn and the corn farmers' lobby into the Google – Yahoo – Microsoft merger brouhaha. Why would Big Corn care about such a thing? Why would a business which receives so much anticompetitive largesse from the government want to spoil the anticompetitive party for other industries?
The answer, sadly, will not surprise you. McCullagh provides a good investigation and overview of the way many supposed "grassroots" groups are formed and operate, and a look at the industry which has become known as the "astroturf" movement.
