Where do developers draw the line with Apple?

Where do developers draw the line with Apple?: "What's interesting here -- from an industry perspective -- is that if you get past the Apple vs. Adobe vs. OS 4.0 vs. what-have-you stuff, there's two legitimate viewpoints floating around. You've got developers like Grigsby who find Apple's model too limiting. So they get out. And then you've got devs who think the App Store opportunity outweighs the obstacles (for now). Dan Pilone, co-author of 'Head First iPhone Development' and founder of Element 84, is in that second group."
