Still, I am convinced that Disney-Marvel don't want their movies to be a total failure and that's their initiative.
For example, in 2008:
As you can see, the Chinese government didn't even need to be on the front line. The collective behaviour of people did all the job.
Yep, my home country managed to piss off both the people in USA ("freedom fries" & Iraq) AND in China (Carrefour & Tibet) and lose sales in the process. As far as I know, it is a unique performance in recent history. Both times, we were right to do so and, both times, it cost us more than it paid off.
On the contrary, Disney-Marvel are sufficiently cunning & opportunistic to apply self-censorship to their movies and there won't be any commercial problem for them.
Not sure how much of that is real, and how much is the dictatorship's 50 Cent Army stirring up trouble.
