As someone who worked on harmful content, specifically suicide and self injury, this is just nuts - they were raked over the coals in both the UK by an inquest into the suicide of a teenage user who rabbit holed on this harmful content, and also with the parents of teenagers who took their lives, who Zuck turned around and apologised to as his latest senate hearing.
There is research that shows exposure to suicide and self injury content increases suicidal ideation.
I'm hoping that there is some nuance that has been missed from the article, but if not, this would seem like a slam dunk for both the UK and EU regulators to take them to task on.
