Social media has significant adverse effects (along with beneficial effects) on society, and the adverse effects are worse outside the US because although the media corporations do try to make their service less toxic, they focus those efforts on US society (because US politicians can hurt them worse than politicians in other countries). The former head of Facebook's effort said that the majority of the effort at reduction of social harm at Facebook were directed at US users and US-based conversations. (I looked for a bookmark documenting that, but could not find one.)
