You probably should not care about it. The only real threat that China poses to people who live in the West is nuclear war, but that is already deterred by mutually assured destruction and in any case the Chinese government having your social media data does not make it any more likely that they are going to start a nuclear war. China's government is a threat to the people who live in the areas that it controls. Since I live in an area that the US government controls, the US government having my data is almost certainly a bigger danger to me than China having it, although to be fair the US government having my data probably is not a very big danger to me either. I find the NSA's activities to be more insulting than actually frightening.
