Is that how combos have worked ever in the history of the entertainment industry or like the world in general? The whole idea of combo is like a buffet meal where you get unlimited access many of your favourite dishes but there are also counters serving dishes that you have no interest in consuming. You wouldn't pay for those dishes given a choice but then if you went to buy the dishes you like individually, you would end up paying even more than you are paying for the combo. So you decide to buy the discounted combo, eat what you like and ignore the rest.
