The short answer is that it would depend on the value of any precision loss that occurred and whether or not the shift would disrupt any other systems, be they social or technical, within the company. But with that in mind, there's also the issue of whether or not the money saved would be worth it. It's very possible that S&P simply has enough money to play with that any savings from swapping to an automated solution for media monitoring aren't worth the potential disruption to the company workflow.
