Honestly, the blocking doesn't make any kind of sense. You can literally create a vpn from within china itself on any cloud provider and surf on anything you want, in less than 10 minutes using softwares like algovpn.
It's now a moment of truth for internet in china : either they start blocking vpns for real (although good luck doing that without collateral damage to the economy, because that would mean shutting down a ton of services), or they just open it.
My bet is that they'll open it. They have services on the same quality as US ones, some even more advanced like wechat , they're already 1 billion user strong, i'm pretty sure they'll benefit tremendously from opening the gates.
