Err.. That should actually cost them more to restrict bandwidth. Because instead of letting the data flow smoothly, they would be capping it, kinda like trying to put 100 PSI of water though a garden hose (restricting) and then trying to put it though 3in PVC pipe. Because the servers are going to have to work harder to keep the data from going out.
Lol, does anyone understand what im talking about
Oh well, anyways, thats absurd.
