Can the damage this caused to society be quantified? Should we let it slide because it's hard to measure? What if I made a website that deliberately set out to sow division and undermine people's mental health, in exactly the same way as Facebook ostensibly does accidentally? Is that allowed? Supposing some people commit suicide because of that? Supposing I know I had that effect, and conceal it? Still legal? How many people in Facebook's infamous A/B sentiment tests committed suicide? Facebook surely knows - does anyone else? Facebook is a problem. So is every company that plays god with our social discourse.
