data caps?

why does cox still have data caps?   it such an old fashion business model? when i lived in california i had no data caps with spectrum or frontier. move to kansas and i am paying more for internet with a data cap. for the price we are paying there should be no data caps anymore. that went away with cell phone plans with a limited amount of minutes. i tried to ask a live agent but he couldn't give me a straight answer. he told me well for more money we can give you more data. Well I am glad Ideatek is coming to my town soon and I will have an alternate choice and cox will no longer have the monopoly in our town.
