Overreaction. Is it illegal for me to talk to your phone? To broadcast myself with a megaphone, in a crowd, and yell "Hey Siri, turn on airplane mode"?
Is it illegal for me to unplug your computer? Jerkish, sure, but illegal only, maybe, in very rare circumstances.
I think you are missing the point. Sure, it's an overreaction but if an individual did it as a prank you can bet some prosecutor would try to make a name for themselves by throwing the book at them. What's fair for the goose...
They're a corporation. Little people laws don't apply to them.
(Oh, how I long to be wrong on this, but I strongly suspect that nothing, or at least nothing that will make the campaign a net negative, will come of the fact that they violated the hell out of the CFAA.)
