By itself, zero-rating does not necessarily stand opposed to net-neutrality. Given how it makes data caps more manageable, even staunch net-neutrality advocates can see areas where zero-rating may be beneficial.
Here's Ernesto Falcon, legislative counsel at the Electronic Frontier Foundation, a consumer advocacy nonprofit that has lobbied against zero-rating as it is used today:
“A more logical usage [of zero-rating] would be if I was a cloud system backup program, if I back up your phone on the cloud, I don’t need a fast internet connection to make that a feasible product. It’d just be a persistent connection to move your files to a cloud backup. I could then, as an edge provider, say, ‘go ahead and throttle my speed, go ahead and make me as slow as you need, to X percentage, in exchange for making me an off-the-data-cap service.’”
“If that was the dynamic, we would be fine. Because it’s the people who are being accessed on the internet, and the users, who are controlling that decision-making process.”
