Why would we even consider jailing parents before banning social media from kids and jailing Mark Zuckerberg for pushing it on them?
The power imbalance between individual parents and big tech is immense.
How can we be mad at random parents for not defeating the most powerful and rich people in history?
Because according to HN there's no way to force social media companies to not serve children without destroying privacy. That leaves parents who aren't changing their behavior because nothing has incited them to change. Legal liabily is an incentive that changes behavior.
