It is however very suspicious knob if most of the spending is automated. To attempt an anology, consider if all phone calls where charged by the minute and there is a knob to adjust the pricing. One cal argue it's a reasonable tool to have. You can turn the knob up to "print money". Or you can turn it up to survive in a time when number of phone calls goes significantly down and you need to cover the fixed expenses. If the price is too low you are leaving money on the table. If the price is too high users will see the costs surpassing the benefits and move to other products. Why not take all the money the market will bear?
