I wish I understood net neutrality. My gamer sons think it’s very important. I tend not to trust a government, not that I trust corporations either. Which is the most freedom oriented way for the consumer?
He uses up some bandwidth although that's not the limiting factor for gaming. He needs low latency. "Neutrality" is the notion that the provider cannot force you to buy their services or some particular service over the one you want. In your son's case, if he is connecting to the game server of his choice and not some shlock server that Cox chooses instead, then his Cox service is neutral. Claims otherwise are specious. To argue that the desire for more bandwidth and lower latency is a desire for "neutrality" is completely incorrect.
