Breaking Down Google's 2011 Revenues

Do these "cost per click" figures actually represent the money Google receives (received) from these companies for every time someone ends up on their platform through the intermediation of Google?
So is this a possible protest vector? Boycotts are frequently called so that consumers can voice their displeasure of the actions of a company. Couldn't a click campaign be used to cause a company a great deal of expense? If enough people purposely clicked enough times, couldn't that get a company's attention? And wouldn't this be just as legal as boycotting?
Google would probably give you an out if they caught wind of it.
The advertisers are the customer, you are the product.
