This doesn't make sense to me. In what way, shape or form can this be more open than Android? Android kernels are open, this doesn't make Samsung's TouchViz open any more than it makes Nokias Swipe open. Still Android itself is open, much more so than Harmattan. When the ecosystem is closed, everything is closed from a user perspective. You use the device to access the ecosystem, that is the basic working principle of a smartphone.
