The most vulnerable part of the propaganda apparatus is Hollywood. Harvey Weinstein showed that they are prone to eating their own, the public isn't that enamored with their movies anymore and the means of replacing them are already all over the place. You can film a feature film on a smartphone, to say nothing of the fancy 4k cameras Youtubers are able to buy and use. And those youtubers and other "content creators" are also proving that editing and all of the other technical skills that relate to movie production are being democratized as well. Remove all grants from movies employing SAG actors, give grants exclusively to movies not produced in Hollywood; watch it implode as they start going on strikes and no one cares.
