This is the issue, it is not a matter of convincing the Chinese people their government is a problem it is a matter of convincing politicians in the Western world that China is truly a problem and pressuring corporations at stock holder meetings the same.
Both need to be told the same thing, doing business in China is not acceptable. Corporations can be forced to change course by stock holders and national or state governments, governments can only be changed by pressure on the political parties in each.
* I own both Tesla and Apple products, my statement on not buying an Apple product made in China needs to be expanded. I will not buy an Apple product or another Tesla until both leave China or the Chinese government changes direction; which I believe will only get worse if the believe the US government slides in weakness or non interventionist form
