Meh he will say stuff like this but I don't think he is either stupid or incompetent enough to not understand you can't dictate how people see and consume art, artist's intent is not omnipotent. You can try to be as "impartial" as you want but if he is truly invested into showing the horror and atrocity then people will make the connection.
This is like making Titanic but not including the speed limit controversy choosing to not willingly vilify Ismay in the movie. He knows what he needs to do to do a good movie, that scene along with Ismay's portrayal as a literal mustache twirling villain is not at all necessary for the movie, yet he added anyway, not because of accuracy either as the real Titanic inquiry testimony is quite different from this. As such a Titanic nerd he knew this would be inaccurate.
So he "knows" what he is doing even if he wont say it out loud, these interviews are just to create buzz, he already got fuck off level money he can do whatever he wants. I only think its likely he is already afraid of Trump affecting Hollywood, [insert subverting expectations meme here] etc... Watch liberals be shocked that the US is shown committing the biggest atrocity ever etc...
