Are boycotts the ultimate form of passive aggression?

They call us consumers, a term I do not particularly care for. There is, however, great power in this role. By our choice of products we can make or break huge corporations. The beauty in this is that it is impossible to tell whether an individual is actually protesting, thus making it the ultimate form of passive aggression.

Suppose that a group like Occupy Wall Street used a computer program to randomly select a group of companies to boycott. The means for making the choice could be made public. It could be an equation based on publicly available information, like the temperature in Chicago on a certain day. If only a small percentage of people responded, by say buying Pepsi instead of Coke, it might be possible to reduce the sales of a company by 10%. That would definitely get people’s attention.
