Those companies argue differential pricing schemes are vital to their success, and should be enforced by US courts I find this sort of reasoning very frustrating. It's not the job of the courts to ensure that anyone's business model can continue to be followed profitably. There may be sound legal reasons to overturn precedent in this case, but "companies are losing money" is not one.
