Reddit is framing the issue like this: Net neutrality ensures that the free market—not big cable—picks the winners and losers
This seems like double-think to me. The net neutrality regulations actually prevent me from negotiating an agreement that models my priorities. It forces me to accept everything one-size-fits-all, explicitly preventing a differentiated market from developing in the commodity of bandwidth.
There are a couple of examples where I think this is relevant.
1) I imagine a hospital that performs surgery via telepresence. This seems a pretty clear area where I would really want the opportunity to pay more, to ensure that the connection between the surgeon and his robot never even suffers the slightest amount of jitter. This is life-and-death, and I can't see why people would object to a right to pay more for higher-priority for this traffic.
2) A few years ago I recall reading about a cell phone provider who wanted to provide a very basic service level that would allow free use of Facebook and a couple of other apps, but going outside of that narrow box would cost much more. Providing to poor people a way that they can participate in the online community seems like a positive, even if what they get is rather hobbled. The idea that we would say to them, "no, you're not allowed to save your money by buying a lower level of service; if you can't afford the whole enchilada, you can't have anything" seems awfully unfair.
