Hacking a law means invalidating its premise through some previously unseen method or principle. No such thing was done here. Wolfe did not hack Metcalfe's Law, or any law, or anything at all. Wolfe is not a hacker. Wolfe is nothing more than a PR rep with delusions of grandeur.
Whether your latter paragraph is correct or not, the rest of your comment is on the money. I do wish the media and others would stop applying the word "hack" to everything.
