I agree somewhat but is it any different from professional athletes? They are being paid a hundred million dollars for kicking a ball.
Writers/actors/directors are kind of different - I would expect them to take a source material and create a show that is true (as much as possible given the media format) to the original source. Ideally without showing contempt for said original material. Either that or create something original - something that has new and fresh ideas. And blindly replacing one sex for another or one color of person for another is not my idea of "new" or "fresh".
To me it seems like they decided that these things don't matter anymore. So I don't mind if they go belly up.
