Yes you do need power to do what Google has done. But having the power to control a think-tank of that size does not require an industry to be nearly as concentrated as online advertising currently is. [Edit] Just think about how much you would have to reduce concentration in any industry so that no corporation is large enough to fund a think-tank and have someone fired. Even if you did that, corporations with shared interests could join together to do the same thing one larger corporation would otherwise have done. It wouldn't be the first time.
