Good question. I was thinking in terms of market share alone. If phone OSs were a reasonably fragmented market, you as a phone buyer could probably choose a phone that doesn't restrict what software you can run and still meet your other requirements (e.g. tight OS & hardware integration). Also, as a software maker no single phone OS company would have much leverage over you. But some of these things could also be argued on principle.
