Obviously a significantly large portion of the Chinese jump the wall to access internet services that would normally be blocked in mainland China. Yet probably the biggest thing still keeping most people from obtaining a VPN service or such, is that almost every major western social internet service has been copied. And if there is one thing about Chinese, is that they love to chat and socialise not just in real life but especially online. Replacements of Facebook, Twitter and other services have such huge user numers that once you see them you start to understand that this is the biggest thing keeping Chinese at bay. Not the firewall restrictions themselves, which doesn't sound that techy doesn't it.
For example, "Youku" which is the most popular video hosting service in China and rival to YouTube boasts a whopping 500 million active users. That's half a billion users which is about the same as YouTube claims to have for each month. While statistics are not always that correct, it is obvious that we are talking about numbers that are hard to imagine without understanding the massive scale.
Interestingly enough, the Twitter equivalent known as "Weibo" in China has seen a decrease of internet users, with still is at an approximated 10 million users. The decline is reported to have been caused by the popularity of another chatting and social software "Wechat", which is nearing again the 500 million mark in 2014.
As I said, numbers are numbers and should not be taken in exact data. However there is just no denying that the Chinese market of social users has been well established, within their own borderline. Consequently keeping the Chinese population happy, enough at the least!
