While this is how the free market works, ironically Apple have implemented the very opposite of the free market. Those who develop apps have also expended capital. If their app is suddenly yanked from the market then you can no longer claim that you are working in a perfect free market.

Incidentally, I disagree with you but I still had to think through my points. I am very surprised that you have been voted down. I upvoted you, I hope some other folks do too - your POV is actually quite germaine to this debate and I appreciate that you have expressed it!
