The Script kiddie did damage, intended to do damage and really did hack. They aren't called a terrorist.

McKinnon didn't do damage, didn't intend to do damage and really didn't hack. And is called a terrorist.

Since the only common thread is "someone complained about access to their compter", there's not a lot of reason to expect us to treat them the same. Just as taking a school photo isn't treated as viciously as kiddie porn, despite "photos" and "children" being a small common thread.
