Some got seriously scarred by last weekend's screw-up but most of them now appreciate that 'black & white' rarely applies to complex project-management & decades old aircraft
I'm sorry to disagree Eddie, but the operation of
all civil aircraft is perfectly black and white, (although the RAF has been known to occasionally use a bit of red ink

).
The operator has responsibility to
directly oversee every aspect of the operation, including any delegated or sub-contracted activities such as maintenance or continuing airworthiness management.
Always.
