You can say that about anything under the jurisdiction of Chinese law. It's not like they have a choice. US companies are also "controlled" by the state in the same manner we are accusing these companies because the Chinese government can compel them to release their data to them in the same way national security letters can be used, and in the same way NSA data harvesting is being used.

The difference right now between China and the US is that everybody knows China is monitoring everyone—even Chinese citizens.
