Facebook has not decayed because of an influx of new users beginning with this "eternal september", but because of the pointed decisions by its leadership to choose greed over respect for its users. The paramount decision is the decision to go public, necessitating indefinite growth at any cost in order to satisfy investors. It must have been obvious to Facebook's early employees that a Facebook at the behest of investors would increasingly dilute the user experience, and yet only now do they lament what they created.
