Business Philosophy vs. Local Laws

Recently, Google has stoped the self-filtering mechanism of Google.cn since China wants to take a further step to restrict the freedom of speech on internet. As what the motto of Google "Don't be evil" and its philosophy "You can make money without being evil" claim, the counteraction is no more than taken for granted. Furthermore, something worth thinking is educed:

Can any country declare it owns the internet or part of the internet by law?

Of course the network infrastructures, servers and other real properties surely belong to some party in some country. However, this never implies the messages and privacies inside are automatically taken possessions of by the owner, not to mention the freedom and rights bound together. As is known to all, the communication channel is an international virtual space so that people all over the world are able to post something for exchange. Here, "international" indicates the network is actually shared, rather than merely owned by some particular country. So who has the authority to shape or put any restrictions on the internet just according to local laws? China, the USA, or neither of them?

The internet is apparently an indomitable realm. No particular country or some kind of doctrine can be the winner to take all. All it requires is self-organization and self-regulation which evolves itself over time. All the communications and message traffic finally contribute and form the memes in the progression. Any other actions taken to influence or force the course of the internet to diverge from its nature should be treated evil, esp. those enacted on behalf of a certain party.

By the way, several days ago, Plurk, a popular internet microblog service, was asked to hand over users' registration details and IPs to the police in Taiwan. The founder of Plurk claims publicly they are willing to ensure local laws as long as the requested measures follow the due process in relation to privacy. Look, Google does obey the law enforcement on internet in China for years. Nonetheless, Google eventually comes back to its original philosophy which must never yield under any circumstances. Hence, we plurkers shall inquire what's the philosophy of Plurk? To sacrifice anything to obey the local laws for business survival is an option, but is it far from evil?
