CNMathon Not sure I agree fully with your synopsis
If VPNs Still Work in China, What Are They Blocking?
The million-dollar question is this: what’s the deal with all this news about China blocking VPNs?
Based on my understanding, it’s really quite simple. China is looking to control the way the companies and corporations access the internet using a VPN (which is what VPNs were originally designed for). Reading the fine print, some of the more recent bans reveal China’s intention to block VPNs for corporations.
China really wants corporations to use government-registered VPN services to secure their data, which honestly is a bit scary. Smaller companies that use 3rd party VPNs will need to make changes whereas the larger corporations that can afford to build a proprietary VPN will need to get it registered with the government.
It all boils down to China tightening its grip on information coming into and out of the country.

This is certainly the case for corporate VPN's - trust me, I've been there several times with an office based in Beijing
