In response to the comment that corporations were formed by cowards: Corporations are formed because people don't want to go bankrupt if some wacko sues them and wins, receiving multi-millions in damages. Would YOU want to be held personally and financially responsible for the faulty design of engineers who work for you if the design resulted in lives lost, a public relations nightmare, and class action lawsuits? Consider how lawsuit-happy our society is today. It started with corporations not acting responsibly. So people had to sue to get any kind of restitution or justice. Which drives more businesses to incorporate to achieve personal non-liability status. Which increases the likelihood of people being forced to sue for redress of grievances. Which drives more businesses to incorporate.... and so on in a vicious cycle.
I'm not defending corporations for their trigger-happy lawyer-siccing, but I wanted to point out that the individual is more powerful than we think. Powerful enough, that a corporation becomes afraid of losing goodwill if any of its trademarks are mischeviously used even once in the silent, yet strangely communicative void of the world wide web.
