Chomsky isn't going to get a lot of power from anything at this point, he hit his stride politically some time ago. If you have read Chomsky's work from early academic stuff up through today, one unifying characteristic is that he is very good at polemics and very apt to it. That style is so much a part of him that it is completely unsurprising that he would use it even on something apparently strange like the invention of email. It's just a long term character trait.
