You are right that governments regulating individuals is against freedom, but this is not what net neutrality is. Money is perhaps the biggest corrupter in human history, and big businesses are built on it. They will always want more and more, even if this doesn't directly translate to a happier customer. They will split up websites into packages, throttle our connections and claim you're not on the "internet fast lane" just to get another buck out of us. It would be as if your electric company offered you a separate package for each room in your house and you had to buy the most expensive one to get power to your entire house. You might be fine with that because you can afford it. I wouldn't be even if I could.
I'm not necessarily for a bigger government. That leaves the door just as open to corruption as it is now. I'd be very happy if the government was but a verifiable distributed rule set. But for everybody to be free, we must not be allowed to hinder that right for others less it eventually happen to us, too.
