If we rephrased the GP post slightly it would say something about creating a system of incentives that, knowingly or not, created these outcomes. It's in fact entirely possible the current system was implemented with no ill intent. The creation of the system itself isn't, as such, the critique. Rather, the critique is how they, after seeing what the outcome of the system is, choose to keep it in place.
These things are complex and unpredictable and fixing it isn't as simple as setting a boolean flag. What we want to see is the public realization from the executives at Facebook that what they're doing is harming vast amounts of people and a decisive commitment to concrete, proactive, and fundamental changes to the system. All of this backed up by short-term visible results in both the short-term and long-term behavior of the system and company.
