I think you don't understand what the comment was implying. If it was open source anyone could build it using xcode and install it in their devices themselves.
Apple's concern was that f.lux changes the color of the screen outside the app, and that fact alone goes directly against Apple's philosophy of keeping apps in their own respective sandboxes. Only Apple is allowed to change UI outside of an app. Consistency at all costs.
