Must have something to do with loss of revenue, somehow. Phone companies aren't quite legit, judging by many of their actions.
I don't know if you're old enough to remember the advent of unleaded gasoline or not but when it first came on the market gas stations had both leaded and unleaded for a couple of years. They charged more for the unleaded and I never understood why they charged more for NOT putting an additive in the gas.
(Because they could I suppose)
How does anyone get away with extortion?
