I don't think the poster was suggesting that 'cancel culture' has affected the chinese political process. I believe they were suggesting that it has created a means for their censorship to be pushed in the West. In so many words; Blizzard can say they don't want to offend the Chinese and use that as their excuse to support this kind of censorship.
My point is that their process is not really being influenced by the so-called "cancel culture" of the last few years.
