The brinkmen will have their way. 
Collaborating with foreign force to weaken reign of Chinese government, especially allying with the West and human right organizations, is punishable up to death in China. It's written in the laws, so what's wrong with Chinese government's move to seize that person?
It is always been used as a political tools -- to allow certain foreign citizen's unlawful actions in China, but when the time comes, this privilege can be taken back by Chinese government at will.
Make no illusion. In China, everyone has to work for Chinese government, even seemingly anti-China propaganda spreaders, such as the Youtuber laowhy86 and his South African friend.
Their videos are very clear that they do bash on Chinese society, but not badmouthing the actual government a lot. Chinese government uses them to spread the idea that it is the corrupted society made the government, not the corrupted government made the society.
Even the hard core anti-Communist cult, Falungong, is kind of working for the current Chinese government. If you read their newspaper, you will see they never attack China's current president. It always attacks the system and more often, the former president, Jiang. Also, their papers are almost intentionally written like BS to discredit themselves.
The goal is very clear -- everyone gets what they want. Current Chinese government wants a weapon to attack the previous government, as it is an ongoing political mass murder. The people who join the cult never truly believed it and only wants US EB4 green card, and the organizer wants donation form big rich Chinese companies seeking political help.
