No, the costs incurred in providing a service is exactly what needs to be quantified in order to determine whether the provision of that service is profitable. If you insist that the contractors must be excluded from the analysis (for some reason), then you have to admit the possibility that the network is being subsidised by the contractors (as would occur if they were operating at a loss), at which point the entire concept of profitability of the network becomes rather meaningless. So you can't exclude the contractors. And you can't simply assume that contractors are unlikely to be making a loss either, because that's exactly the question that we're asking.
