This is all meaningless.
It's just corruption American style.
To actually change behaviour you would need immediate detainment of all senior leadership (have Zuckerberg in underwear, with a bag over this face), immediate, potentially indefinite, shut down of FB/Insta, house arrest for all employees above 25 (if they are not a flight risk).
But most importantly you need a real court and judicial system that wouldn't hesitate to apply full asset seizure (potentially expanded to cover family and close business partners) and would focus on real community service programs for rehabilitation (repair work in Chernobyl, de-ming work, junior janitor work in an infectious disease hospital in rural Africa), with a year of community service given for every median local annual salary in damage.
