How is Apple a “monopoly” with less than 20% of the smart phone market?
100% of that market. The apple app market is not the same as the android app market. They're not in competition with each other. Owners are captive.
They’re the only taco store on this block! I demand the government force them to lower their prices so I don’t have to walk more than 50 feet!
If you don’t like it, switch to Android. But of course, the real problem is that people don’t want to switch to Android. They want to have their cake and eat it to, but that’s unfair and illogical, so they start slicing down the market to where they can cry monopoly and ask the government to force the business to give them what they want.
