Knowing a bit about how sausages are make (not at Apple specifically), I'm willing to bet that this isn't as much "withholding features" as "getting on the hype train asap, but doing it in a DMA-compliant way would delay the launch by far too long".

Also, it should give you a pause to think what is it about their intelligence features that is not DMA-compliant and why would the rest of the world want that stuff in their pocket.
