As an anon who lived in China for a couple of years, I can confirm this. Like Facebook and Amazon, they are mere extensions of government, except that in China it's much more obvious. In fact, social media that does not toe the government's line and hand over information freely gets banned; meanwhile, Chinese copy-cats are regularly praised as being "more innovative" despite only filling a void that has developed.
The Chinese government is enigmatic and hard to characterize except for one word: paranoid. It dodged the bullet of total Soviet-style collapse in the 1980's by opening up trade, cracking down on protests (NEVER bring up the Tiananmen Massacre outside of a closed room), and purging the government. I doubt that it's closely linked with the (((globalists))), but it wants to reign over its corner of the world and will enforce this by any means necessary. If a serious rebellion broke out, the image of China as a stable homeland (a holdover from the "Mandate of Heaven" from Imperial times) would be damaged and even if the rebels are unarmed the military (who really runs the show) doesn't want to kill potentially millions (it's bad for business, to say the least).
Keep in mind that the Chinese people already kind of take it for granted (though they have no idea of the extent) and most really don't care; those that do wisely shut up about it or they will be silenced. They really are "ant people" in this sense, as respect for authority is considered paramount and privacy is a foreign word to them. They are given Marxist indoctrination in high school and are discouraged from developing critical thinking skills. It's one of the things we want to avoid becoming in the West (at least the Chinese aren't racial mongrels and are becoming wealthier). However, it isn't a new development as back in Imperial times Chinese subjects would have their head lopped off simply for drawing a dragon or wearing yellow.
As for getting past surveillance, it's not easy but its doable. First avoid social media (duh); I never use QQ and my main function on WeChat outside of work is to s-post in a group of American expats, many of whom are left-wing losers who can't do anything beyond teaching English at an abusive second-rate school (hilariously, my efforts have sort of redpilled and driven the rest over to the right, and making fun of SJWs in the group is now common). If you buy anything from Taobao/Tmall/JD.com (Chinese versions of Amazon) make sure it's not suspicious or get a friend to order it for you. It's difficult to find an ISP that won't track you if you're not a native speaker of Chinese, but the standard "full monty" privacy setup of virtual machine+I2P+VPN (though China has been cracking down on VPNs as of late, more expensive premium versions still work and are highly worth it) should help. It's not going to let you live completely on the down low, mainly because of the ubiquitous street surveillance (though wearing masks is permissible and commonplace because of the pollution, if you're any race other than Asian you'll stick out like a sore thumb).
Although constantly being watched peeves me and makes me paranoid, I don't consider it a threat as the (((globalists))) are whom I have beef with, not the Chinese government. As long as you're a good little citizen/foreigner and don't get into fights or spread counter-propaganda they'll leave you alone for the most part (I'm not giving them my fingerprints, though).
