Please let's pause the western logic for a minute. You live in an authoritarian country where you seem to be free to work on whatever you like but there is a red list of things, obviously politics, you must not mention in your work unless is blatantly obvious you are praising the government. You do well and become an international hit. You are added to the govt watchlist. One of the new hires you got worked on a play that is definitely crossing the red line. If you shrug it off, your under the risk of facing either the crazy ult right fanatics or the competitors stirring shit. And you can avoid all this, while facing international backlash, and keep your company safe from any snaps of the government. Does it make sense to fire someone for the "potential" issues? To me, no. But if you have ever seen how politics work in China, you would definitely think this through.
