I believe that Net Neutrality rules specifically tell an operator how to configure their networks.
Yes, like telephone networks. It's illegal for your phone company to see you are dialing 1-800-coca-cola and redirect your phone call to 1-800-pepsi-co. But for your Internet connection, that was 100% legal (and done, in many cases).
They specify that a network operator is not allowed to use certain QoS configurations.
Yes. They are not allowed to use abusive QoS configurations. They are perfectly allowed to use every QoS configuration I've ever seen someone assert is illegal. You can prioritize voice over video, and both over HTTP, or whatever you want. What you can't do is prioritize *your* video service over a competitor's video service. You can still block (or set QoS to the absolutel losest level) P2P and the other things that many were saying they couldn't do.
So, what QoS profile were you looking for that you think is illegal now? If it's not one that benefits your service at the expense of a competitors, or is used for extortion practices, it's legal. So I don't believe you that there's a reasonable QoS profile that is now illegal. Sure, there are some that aren't allowed, but those are only the abusive ones.
They specify that a network operator is not allowed to use certain policing/metering configurations.
policing is QoS, so I don't understand how this is different than the previous statement, also I only hear "metering" as a user billing issue, and it's unrelated to any "configuration" in the network.
They specify that a network operator is not allowed to use influence the routing of traffic within their network.
No, they don't. You can still influence the routing within your network.
Sounds like all your problems with it are from your misunderstanding of it. The reason you were called a Republican is that you are parroting all the disproved talking points the Republicans are using. But not bringing up any valid objections.
