That is because the system (organization) prefers its nodes to be legible rather than illegible. It might hear that some nodes are "more productive", but that is illegible and unauditable from the system's point of view. In light of this, I see no reason why employees shouldn't conform to the metrics; yes, some "true productivity" is sacrificed, but that is the price of legibility. That has always been the price of legibility, whether you're a state or a company or a community. For large organizations, that is a price they often choose to pay.
