I like Lexus and I like iPhone. Lexus is my favorite car and I will only drive a Lexus iPhone is my favorite phone and I will only use iPhone I can buy Lexus ONLY from a Lexus dealer I can use iPhone ONLY with AT&T I am not limited to buy a car other than Lexus I am not limited to buy a phone other than iPhone So I choose to buy a Lexus and I choose to buy an iPhone. No monopoly so far. But, what would happen if Lexus requires me to use only Allstate for my Lexus' auto insurance because Lexus and Allstate have an exclusive deal with each other? Or, what if I can only get oil change either at Lexus dealer or Jiffy Lube because Lexus and Jiffy Lube have an exclusive deal with each other? If I don't have auto insurance with Allstate or receive oil change from Shell gas station, Lexus won't honor my warranty and I have to pay the full price for any repair. Yes, I agreed to those terms and signed the document at the Lexus dealer before I received my car keys. Also, I am free to go to any repair shop and have my Lexus repaired without warranty. So, while Lexus is not "forcing" me to buy auto insurance from Allstate and receive oil changes from Jiffy Lube, Lexus is practically limiting my free choices to one insurance company and one oil-change place. Some people would say it's no monopoly because no one forced me to buy Lexus at the first place. Well, it might not be a "monopoly" in a strict sense. But, it could well be a violation of consumer protection laws because it practically limits consumers' choices to only one service provider. I believe that violates perfect competition as well.
