I don't see what problem you're solving by open sourcing, therefore this is just a misguided publicity grab.

* The "open letter" goes from addressing Apple to addressing potential developers.

* What does open-sourcing give you other than people to help you write code for free? You still can't put the app on the app store and therefore can't release it to users.

You can get it on third-party app stores instantly already.

If this hiccup is going to stop you creating new things, you're not going to get far.
