Austin’s point about blocking youtube is well taken. I too pretty much ignored the videos as being hard to verify (though they look convincing). But in the last couple of days a bunch of people have asked me about the youtube blocking and what caused it, and if Austin hadn’t beaten me to it, I was going to post about. . For the record, incidentally, the youtube video isn’t the only one. There are two more videos here. All require getting around the Great Firewall of course if you are in China.
