It does not consolidate monopolies because, by law, ISPs are required to add all apps from a category (chat, video, etc) to zero-rating. i.e. if you add Netflix you are required to add YouTube, etc.
All I see about NN is a lot of manipulation from both sides. And what's especially frustrating is that some people insist that NN is anti-customer. No thanks, I'll keep my zero-rating.
