China corrupts any global organization it touches.
Imagine what China is gonna do to Apple now that on-device wrongthink scanning is a thing.
Yes, it's horrifying how the authoritarian Chinese government forced this.
The Transformers series especially wound up being money printing machines in China.
Even overlooking the pressure China doubtlessly applies to Hollywood, the execs greenlighting scripts would have to start hating money to approve anything that jeopardizes revenue from Chinese theaters.
International inter-governmental organizations have always had members like China. That is the environment they are built for and function in, like the current, waves, and wind for a ship at sea.
The U.S.'s reputation isn't so hot, throwing it's weight around and under Trump and to a lesser degree, GW Bush, actively trying to undermine those organizations. Even the international postal organization was a target.
Actual corruption can still happen by individuals within organisations, but that (continuing the metaphor) is like coughing or stammering while you talk, and isn’t desired even by the user.
