Whether Taiwan is a real country or not, banning references to it is just tyrranical.
Imagine if the US banned you from selling software that made reference to the lost city of Atlantis. Clearly wrong.
It is oppressive that the US government won't let free people do business with people in Iran and Cuba, but it's not the same thing as banning people from acknowledging that those places exist.
I don't think it is that obvious. Particularly if you take into account China's long history
What reasoning would support the idea that the PRC represents a legitimate government and not the ROC?
Even if you don't take a stand on whether Taiwan is a real country or not, it is wrong to ban people from selling software that purports that Taiwan is a real country. How is this not obvious?
