Chinese oversea student here.
Just taught my gf how to use WhatsApp on her phone last week because we were tired of the poor video chat quality on WeChat and the video call on WhatsApp was surprisingly good. We planned to have another video call this Wednesday. This news is so frustrating.
I just can not make sense of this kind of censorship. It is so sad to see China slowly drifting to a similar direction of North Korea. At first it was YouTube. Then it's Google search. That's understandable because yeah, there really is a lot of fake news bashing the Chinese gov out there. PPTP, L2TP never had worked. OpenVPN got filtered out. SSH tunneling got detected too, even with obfuscation. I had my best experiences with Cisco's VPN protocol, but it was hard to find a provider with that option and I suspect the traffic was monitored as well because the gov had actually worked with Cisco. There was then a protocol called ShadowSocks, which served me well until I moved to study abroad, but the original maintainer was then threatened by the gov and moved away from that project.
I support my government fully for all their effort on making the country and economy stronger and its people's life better. I understand the censorship of neo-nazi propagandas and the like, but is this much censorship really needed? Very few people in China use WhatsApp. Those "bad guys" will always have resources to go around censorship. Good citizens with lawful needs don't.
I suspect China's AI ambition has a lot to do with more advanced censorship. When still using ShadowSocks, I stumbled across posts on how the GFW (Great Firewall) was implementing machine learning to detect ShadowSocks traffics. Looks like China's global "inter"-net firewall is really slowly changing into an operation based on whitelists.
