In the article, one of the contractors says that Cognizant puts up a "dog-and-pony show" whenever FB executives visit. Again, it's ultimately up to FB to decide how much they want to push past the facade.
This downward pressure ends up directly impacting moderators. Cognizant needs to keep payroll costs low so they don't lose the contract, and the contracted accuracy target of 98% seems unrealistic. So moderators end up fearing for their jobs when they don't meet accuracy targets.
