Facebook and Apple have tried to negotiate something for a long time now and both have had a hard time coming to an agreement on working together so it's not that Apple doesn't want to integrate with Facebook but rather more than likely nothing has been hashed out on terms both sides could agree to. As for what Apple stands to gain? I don't know for sure but it would be a good experiment for them to see how many people would use a social feature like twitter when integrated and how people socialize and leverage that data both for learning how to improve their own social elements as well as maybe strike a monetary deal later. Who knows. It's too difficult to speculate. For all we know, its just good UX that could draw in more love for Apple products.
