When this is good: when the bounds of permission are set by an entity which has no legitimate right to restrict an action. See: Rosa Parks sitting at the front of the bus. When this is bad: when the bounds of permission are set by an entity that has all legitimate rights to restrict an action. See: Police officer tasering someone in a case where it's not necessary. Bringing down the level of seriousness a few notches, it's interesting to think of what these brightlines are and how wide the gray area is between them. For instance, was Google's launch of Buzz an abuse of the permissions users had granted it for email? What about Facebook's feature rollout earlier this summer? When does a service provider cross the line when it provides new functionality that its users may not have explicitly asked for or agreed to when they signed up?
