> China proved the Great Firewall was possible.
Technologically? Maybe. Practically? I'm posting this while using uncensored Internet from within China, and not because I'm going out of my way to evade any blocking.
The GFW is more like the government put out an umbrella, but nothing is really forcing anyone to stand under it. Five steps and you're out. No doubt they could change that tomorrow if they so wished, but there are hurdles other than technical ones.
In my case I'm simply roaming using my German SIM-card, but plenty of VPNs would work too. They can detect and block these and do with certain ones, but for many they just... don't.
