Re: Genuine question (and maybe that's not the point of the article).
Nothing wrong with pushing Tbits if you pay for Tbits. It's if Netflix or their customers are charged more because it's Netflix Tbits instead of Google Play Tbits or Apple iTunes Tbits.
Neutrality means even playing field, as supposed to anticompetitive pricing. Like "oh, your email is from John, so I'm charging double because I like Fred and he pays me back handers when I sell servers..."
