And my favorite article, which supports the first paragraph above, is about Google and Amazon. Remember, there are two parts to net neutrality: Content and Service. Amazon, Google, Netflix, Facebook, et al are the Content providers; Comcast, AT&T, Verizon, Time-Warner, et al are the Service Providers.
If you have Amazon devices, and are trying to visit YouTube, you may see a message that says "YouTube will no longer work on this device after January 1." This is because Google is feuding with Amazon. Remember, these are both content providers. In other words, you have two content providers who are opposing the FCC proposal next week and are allegedly staunch supporters of net neutrality, that are limiting what you and I, the consumers, can access.
Not quite. You can get YouTube and you can get Amazon Video on Comcast. Because of the Amazon/Google feud, you might not be able to watch YouTube on Amazon branded devices, like the Amazon Fire or the Amazon Echo. Meanwhile Amazon won't sell Google Chromecast devices. But hey, I've got a smart TV with the YouTube App and the Amazon Video App. My service provider is Comcast. I can watch either one of these content providers. The feud is over the delivery devices used to see the content. The service provider doesn't even enter into it. This really isn't a net neutrality issue.
The better analogy would be Betamax and VHS. Or Apple and Android.
In the 1980's we'd go to the video store (the service provider). We'd look at video tapes of movies from MGM, 20th Century Fox, Paramount (the content providers). We'd choose the delivery system (Beta or VHS) and go home and watch it on our hardware devices.
Apple apps don't work on Android devices, and vice-versa. VHS tapes didn't play in Betamax players. YouTube isn't going to play on Amazon Fire devices.
