I guess I don't see why this is even worth arguing. Even if you're right, where was it written in stone that nothing about the arrangement could ever change?
Are you seriously arguing that it would have been impossible for Disney to preserve AC and CW by just...ya know, changing the budgeting and personnel practices for the area? Your argument seems to hinge on an assumption that once a company makes up a set of operating procedures, it's powerless to change them. I guess I'm having trouble seeing why that should even be treated as a serious position. :shrug:
