I would assume so. They have not taken any thing down until now, as far as i know. This is the first time i have noticed something like this. It is a production from them, so copyright should not be a problem ether. But i do know that France and China have a "good" relationship, as they say. And i have not found any statement why it has been taken down. The content of the documentation was very open about the dangers of a new Chinese global Empire. I think that might have been the issue, but who knows if they de not tell you why something got taken down. It was on YT and there Homepage, both gone and no say why!
