No more than it would be OK for government apps to support only iPhone.
What's your point here? AFAIK, there aren't any important government apps or bank apps that are exclusive to the iPhone, nor is there any pressure Apple is putting on banks or governments to be exclusive to them.
It sounds like you made a completely unjustifiable leap from "because of the popularity of the iPhone, governments and banks need to make sure they have iPhone apps (because it's discriminatory and irresponsible of basic services like these not to support a widely-used computing platform)" to "Apple is forcing governments and banks to exclusively support iPhone".
