I understand that is how that the market works. It may not be a "problem" in people's current understanding of the law, but I certainly think a problem is being exposed here. I am arguing that Apple has created something different with the AppStore; a privileged sub-market. Because the burden of changing markets is heavily in Apple's favor they should, as a large public company, be required to serve the public good and manage it in the consumer's best interest, not their own.
I can understand what you mean, but isn't the consumer's best interest sort of... subjective?
Apple has obviously gone to great lengths to make their walled garden a reliable and safe place for consumers who have chosen to buy their products. If you talked to Tim Cook or Jony Ive, I bet they would make a case that the best thing for consumers is to be entirely invested in the Apple ecosystem. After all, it DOES give you the most consistent experience.
So if you look at it from that perspective, who's right is it to go into a company and say, "No, that's not what's best for the consumer!" Obviously people like what they are getting, otherwise they would be defecting to Android in droves. Contrary to what some people are saying here, they DO have a choice.
Thinking through it logically, I just can't see any scenario where a company, no matter how large, should be forced to push a competitor's products.
