How? My ISP wouldn't be prioritizing Netflix's traffic across my network over any other traffic. All the Open Connect CDN servers do it make it unnecessary for the traffic to leave my ISP's network. This is effectively how all CDNs work. CDNs do not violate Net Neutrality. Allowing peering points to become oversubscribed and expressly using that to extort money from content providers did violate NN.
Here's the thing with all the ISPs who throttled Netflix: when they signed up to be an ISP, they were agreeing to be a dumb pipe in a regulated industry (telecommunications). The fact that they later decided they didn't want to be a dumb pipe any more, for whatever reason, is immaterial. If they didn't want to provide enough bandwidth to keep the packets flowing during peak times, then they should've suffered the consequences by losing customers.
Unfortunately, in most of the US, broadband ISPs are effectively monopolies. If you are a monopoly in the US, you either get regulated or you get broken up. NN was the regulation that the monopolies got. People who are against NN say that the government shouldn't be interfering in internet communications. Fine, but in the absence of ISP competition, the only other option is breaking the big ISPs up, which doesn't really help anyone. The government can't really sponsor competing businesses to come in to monopoly markets either, so that puts them in a difficult position. NN was the lightest touch the government could have on the industry while still performing their responsibilities, but the industry rejected it, so now we have a mess instead.
