I would guess they have 95% of the 3D mobile games market now.

And I didn't say they have additional responsibilities to the market at all. I was just making the case that to limit choice of your partners (and, therefore, your consumers) to kill your competitors is evil. It is what Microsoft did with OEMs and it is what Apple is doing with developers.

Is is perfectly possible to kill a competitor without being evil. The best example is Facebook. I don't think Facebook would ban a developer for using a Google API or a compatibility layer that make games work in Myspace too. They even allow multiple payment platforms!
