If I have the market power through mono- or oligopsony to force my vendors to sign fixed-price contracts for variable-scope work, I guarantee you they aren’t getting paid for a lot of that scope, whether that comes out of their bottom line or their employees’ lives. Hypothetical me is going to improve my own bottom line by pushing scope (“just fix it in post!”) to the part of the budget that’s contractually-guaranteed to stay fixed.
