If you want to condition people that a site is bad but more subtlety than a outright block, it is a viable method. If you can visit it, but every time you do you are misleadingly told it is malicious, then that may have a subconscious effect (assuming you don't disable it outright), and you don't have to stop everyone from visiting to influence society as a whole. In fact, there may be cases where being blocked by the Chinese authorities lends credibility to site, whereas being flagged for malware does not. These are definitely edge cases, and no doubt the China government would to completely block a site in most circumstances, but it is another tool they could use. It also increases their coverage - the current censorship tools only cover China, but this covers any _device_ where the region is set to China (meaning it can apply to some people outside of China, and continues to apply to people who have temporarily left China).
