Most informed people on the issue aren't arguing that Apple should treat the App Store like it's a free market. I quite agree - it's not, and Apple shouldn't have to make it so. What people have a problem with is the inconsistency. Apple has intentionally made the App Store a major business platform, and start-up developers invest a great deal of time working on those Apps. When Apple begins to harm developer interests inconsistently and only in accordance with their own interests (regardless of obvious obligations), then people have every right to complain.
