Good question. It is unlikely that many real iPhone devs are upset with the rules regarding 3rd party frameworks. Here is a portion of my comments on mobileorchard On the question of cross-platform tools, I think the old dev agreement did have some language against using 3rd party frameworks. The new dev agreement makes it much more explicit/clear. If I wanted to develop Android apps, I wouldn’t expect to use Cocoa-Touch and Objective-C. Similarly, I don’t need .NET or Flash to write iPhone apps. I like the Apple platform and code to it. It appears that Apple wants to limit their app-store to developers who want to work with their platform. I think this is a legitimate desire. From Apple’s perspective, it helps iPhone users by improving quality and reducing quantity in the app-store and it also helps developers who invested the time to learn Apple’s platform. Obviously, it also helps Apple if developers use their platform directly instead of going through middle-men. Overall, I don’t have a problem with Apple’s policy.
