First, there isn't a clear line between "the common person" and everybody else. Every first-time user, whatever their age, is a potential power user, if they aren't taught to be subordinate to a remote corporation in the control of their own hardware.

Second, many "uncommon people" are the sons and daughters of "common people" and will learn to hack -- or not -- on their parents' computers.

Common thread: helplessness can be taught and learned. It's convenient for Apple and an inevitable state anyway for many users, but it keeps other "users" beneath their potential.
