As it stands, Americans can consider information presented by foreign governments. We do not block your attempts to communicate with the people in the United States. But citizens in societies that practice censorship lack exposure to outside views. In North Korea, for example, the government has tried to completely isolate its citizens from outside opinions. This lopsided access to information increases both the likelihood of conflict and the probability that small disagreements could escalate. So I hope that responsible governments with an interest in global stability will work with us to address such imbalances.
For companies, this issue is about more than claiming the moral high ground. It really comes down to the trust between firms and their customers. Consumers everywhere want to have confidence that the internet companies they rely on will provide comprehensive search results and act as responsible stewards (a bit off) of their own personal information. Firms that earn that confidence of those countries and basically provide that kind of service will prosper in the global marketplace. I really believe that those who lose that confidence of their customers will eventually lose customers. No matter where you live (sounds like leave to me), people want to believe that what they put into the internet is not going to be used against them.
