The Great Firewall has descended; few communications today. The Iron Curtain has fallen on HK. More brutal than the old Soviet methods. To be behind the Great Firewall means you can't access many websites without a VPN, which, itself, can be shut off. If it is, Hong Kong will no longer be a global financial center, but merely like Shenzen or Shanghai. Everyone knew this day was coming; that’s why everyone was on the streets. This was the Alamo.

Depends on the person—neither Gordon nor I should. All we can do now is apply political and economic pressure
