It's a responsibility, probably (definitely, I think, but minimally probably) the most important job and responsibility one can have. If you're on HN, then you likely recognize the brain rotting effect of social media without moderation, and if that's the case, your responsibility is to parent to the minimum amount that you moderate your kids' usage.

Yep. And people parent harder by banning social media entirely. Problem solved!

this is exactly what hard parenting is all about. I do “as long as you under my roof…” bit (6 more years to go…) :)

I think the problem is that parents don't know that it's bad so they don't limit but this CEO apparently knows! Many parents are addicts themselves

honest question - do you really think that (most) parents do not know that it is bad?! This “CEO” stuff is not new, Steve Jobs famously said the same thing about his own devices…
