Apple annoys me with how closed off they are in many ways, but this is the example I always bring up when people are trying to HATE Apple for being so closed off - they destroyed the most destructive force in mobile UX ever - the phone company oligopoly. Besides also presenting the only ever true competitor to the Microsoft PC, that's their biggest contribution to openness (whether done intentionally or not).
