How strong of an incentive do we need to ban an app? Should we ban apps made in Brazil, because the BRICS nations are considering making an alternative to the US Dollar? That's pretty adversarial. Or maybe apps made in France or Japan, because some of their companies compete with ours (especially in telecom)? And what about people who get in the way of progress, such as anti-war protesters? Not a slippery slope argument, I just want people to think about where they draw the line. There are no wrong answers,.. just... tradeoffs.
