They're the only vendor for the Mac platform and one of two competitors for mainstream desktop OSes. Tell me they don't have market power. It's just...self limited to a niche of a bigger market.
Microsoft also happens to be the only vendor of Windows. They get to dictate what goes in the OS, what is left out, what technologies they'll support, what APIs and development platforms will exist in the future (MFC, C++, .net). Is this a problem?
Also my Hotpoint dishwasher at home has a circuit board that I can only buy from Hotpoint. Does this mean they are abusing their position? Should I expect to be able to run something else on my dishwasher?
My car is a Volkswagen. I cannot take engine management software from a Chrysler and put it into my Volkswagen. Yet Volkswagen is a very large competitor in the "car" market. Does this mean that Volkswagen is abusing its position regarding the engine management software in my car?
If I am right, you are saying that Apple has a monopoly of power inside its own operating system. Yes, I think that's correct!
Where I work, my company has a monopoly on the features and timescale in the application software that we develop. I don't think anyone would ever call that a monopoly in the true sense of the word. Would you let me dictate what features go in your software?
Why would Apple let anyone else tell them what should go in their software?
