Cory Doctorow goes on to discuss that as well in the next paragraph after the one I initially posted, when talking about banning hands-free kits in cars:

"We understand that cars remain cars even if we remove features from them. Cars are special-purpose, at least in comparison to wheels, and all that the addition of a hands-free phone does is add one more feature to an already-specialized technology. There's a heuristic for this: special-purpose technologies are complex, and you can remove features from them without doing fundamental, disfiguring violence to their underlying utility."

Computers and software such as Google and MegaUpload are not special-purpose enough that you can make legislation about their design without "doing fundamental, disfiguring violence to their underlying utility".
