I don't think that's part of the developer license agreement any more. Considering how successful Unity, Corona and other non-obj-c development tools have been I'd be surprised if it was.
Don’t know. The last I heard of it was mid-2010, and there doesn’t seem to be new information saying it’s changed. Apple seems bent on killing Flash, and that wording was a perfect way to deal with CS5. Unity, on the other hand, has a good relationship with Apple, so there’s no reason for Apple to invoke Dread Section 3.3.1 against them.
