No, you say. I am the customer. You explain that you want your new automobile to run on Perrellis, and you want them to sell you a car with Perrelli tires installed from the dealership. They again refuse and tell you that they cannot sell you a car without Bill's Motor Company Brand Tires. You offer to buy the new car without the tires and will pay for the Perrelli tires sepatately because you want to install your tires at the dealership. This they refuse to do, maintaining that they cannot sell you a car without Bill's Motor Company Brand Tires.
You offer to pay full price for your new car, and ask that they not install tires at all, because you will go to a third party shop and install new tires. They still refuse, but this time they make the claim that your new car will not run without Bill's Motor Company Brand Tires installed on your wheels.
Another lame, brain-dead metaphor.
Again, if want the car metaphor, look at it this way: You tell Steve "I'd like to buy this car, but I don't want the engine."
Steve tells you "sorry, I can't do that, I'm under contractual obligation to sell the car with the engine."
You become irate, and accuse Steve and the manufacturer of ripping you off.
Steve tries to explain to you that most people want an engine with their car, and by buying the car with an engine installed, he's able to buy the engine for a fraction of what it would cost for him to buy them separately. The only "catch", he tells you, is that he's agreed to only sell cars with engines under the hood.
This only makes you angrier, because after all, you have a right to buy a car without an engine, dammit, you're an American!
Steve then tries to suggest that you go to one of his competitors (!!!) who doesn't have the same agreement, but, if you do that, you'll have to pay full price for an engine, because by avoiding the car-with-engine agreement, they don't qualify for the insanely inexpensive engine pricing.
Upon hearing this, you explode with rage, and scream "see you in court, a$$hoal" into his face, and storm out, slamming the door as you go.
