This is a non-issue.

As an example, the rest of the world hasn't mass-adopted Baidu and isn't going to. The same has and will go for most of China's services.

Baidu is heavily shielded from external competition due to both nationalism and government controls (censorship etc). A protectionist's dream? No, a trapped nightmare, they can never compete properly with Google on a global scale. Seeing as China represents about 10-12% of global GDP, Baidu will never derive a meaningful business from perhaps 3/4 of the global economy accordingly.

Live by censorship, die by censorship.
