Generally glad that the order was upheld. I do wish that zero rating was more clearly defined, but regulation is just as much a reactive task as a proactive one, and it will be interesting to see how the ISPs use that tool in their toolbox. My suspicion is that we would see general price increases but then a 'zero rating' for, say, streaming video, making it seem like a good deal. Video seems cheaper but is really just subsidized by the rest of the content.
I see a parallel there to how the health insurance situation in America seems to have played out over the last few years from the view point of the average middle class developer.
