Capitalism outweighed any risk of negative reaction. It's also bread and circus. Considering incels are becoming a major male demographic, more blackpill content will get them back into the theater. I think the entire "outrage" from the media was an intentional media campaign in itself, or at least the producers egged the journos on.
As things get worse your oppressors will have to throw a bone lest the guillotines come out. So if you once or twice a month tell them you "feel their pain" with a disingenuous smile, most stupid plebs will eat it up. Think of it as a steam valve, you have to let a little out unless you want the whole thing to blow up.
I think the movie played up class division with the whole "kill the rich" thing. If he had been brutally rejected or oppressed by women it would have been more of an "incel" movie. It also had an injection of wokeness with the interracial coupling, only white men committing violence and crime, off screen death of all the females, etc.
