Your congestion is from the $10/month people from whom you could not be protected. These people have no priority over you in a net neutrality world.
You pay for a high speed, but its only burst speed and not a minimum guaranteed rate because you cant be prioritized over the freeloaders.
My point is simply this. If Net Neutrality is removed then the new rule is "if you want MORE than you'll PAY MORE".
My understanding is removal of NN means free enterprise dominates, which means there will be NEW plans costing MORE if you want MORE.
