An interesting aspect of this is that this is an online protest on a platform that the Chinese government doesn't control. They normally exercise strict control over their internet to prevent movements from getting out of their control (for example, censoring #metoo when it starts trending). Would the Chinese government be willing to block GitHub? Surely that would be damaging to China's tech industry.

What if people started creating repositories with nothing but information about topics that the Chinese government considers sensitive (like the Tiananmen Square massacre or other human rights abuses)?
