Look, why does everyone think China is involved? Just because the IP addresses point in that direction? Weak sauce. Here is a much more nuanced way to look at things. Yeah, they use China IP addresses. But much of the high tech part of China is on the eastern coast. This is part of the Pacific Ring of Fire, a whole bunch of active and extinct volcanoes ringing the Pacific Ocean.
Now, there aren't a whole lot of fiber optic cables that run directly to volcanoes. The business case really isn't there. So, if you are an evil villain bent on world domination, holed up in said geologic structure, where would you get Internet access from? AT&T? Comcast? Nope. You're neighbors in friendly, capitalistic China. You can even pull some plausible deniability out of it.
Come on guys, think harder. What kind of world do you want to see? Millions of plastic knick knacks at Wal-Mart.
Or sharks with lasers.
