:Caps don't manage congestion during peak hours. The "heavy users" aren't affecting anyone if they're downloading during non-peak hours. And even the light users are slowing everyone down by checking their mail or listening to music during peak hours.
Caps are nonsensical and anti-competitive and there is absolutely no evidence that indicates they do anything to help manage network traffic.
Caps are just to give a limit for abusers. The Congestion Management is to manage congestion during peak hours.
