>This is an incredibly disingenuous description of the situation. Facebook's own (non-public, now publicly leaked) research indicates that Facebook causes harm to teens mental health. The only "US narrative" here is the one backed up my the incredible amount of research supporting the growing issue of mental health in the US (and the world for that matter).

This is disingenuous, that same data shows the majority of the teens surveyed said FB improved their mental health.
