I think what the creator of the video does not understand is that intellectual property laws do not really exist in China. Virtually everything imaginable is freely available on the “walled” Chinese internet: copied movies, games, music, television shows, Youtube clips, and and much more.
The content owners (software developers, movie studios, game developers) have almost no power to rectify the situation because China does not abide by international law (it abides by China law). There are some exceptions to this, like very powerful and influential movie studios and such. But things like people who create popular content on Youtube have absolutely no chance to prevent their content from being stolen in China. Because they have no control over it, I think it’s in their interest and not try to chase down people who copy their content, because (at least in China) it will be a useless pursuit.
