There is hardly any activism against the invasive surveillance of SV companies or protests against the NSA. This forum itself has its fair share of apologists for surveillance capitalism. Where are the protests in front of Google and Facebooks campuses and in Washington?
So if people don't care about these issues at home how can they care about them in China? This is simply not credible or serious.
China's actions don't impact you, your governments and companies here do. In the absence of any mainstream activism, just singling out China for outrage and anger is duplicitous and comes across as motivated more by politics than any genuine concern for the issues.
