Instagram certainly has an ethical obligation to act on this and improve the situation. At the time that I left Instagram in early 2020, there were more people working on improving wellbeing, particularly for teens, than working on trying to improve engagement. I wasn't specifically tasked to work on well-being, but like all engineers working on recommendations I was required to work with wellbeing and completely address all well-being concerns before shipping anything.
