No, it was rhetorical. The point is the charge that MAC spoofing was relevant to was unauthorized access, but if MAC spoofing is sufficient to prove "unauthorized" then MAC spoofing would virtually always be unauthorized access to whatever you're accessing with a spoofed MAC. That interpretation would make MAC spoofing illegal without any underlying crime.
>when the charges are federal crimes, prosecutors decide whether or not to press charges. not wanting to press charges does not magically make criminal acts not criminal.
I'm not sure that's always true. If one of the elements of the crime is that what the defendant did was unauthorized (as was the case here) then if every victim authorized the behavior that element of the crime wouldn't be satisfied, no?
