The main discussion here about offering this for kids. So, no! "if it's harming your mental health, stop using it" is not appropriate.
Maybe kids shouldn’t be using it. It’s reaching the point where parents aren’t doing their jobs so the government should ban it to protect the kids.
Just like tobacco, alcohol and porn we didn’t make it cancer and addiction free or remove the nudity - we banned kids from accessing it
Banning something just for kids is an easy win for any politician, since that's one of the few groups that can't punish you in the next election. For that reason alone, I assume we'll get some law within 5-15 years mandating that Facebook ban kids. I assume the kids will trivially bypass it the block, or switch to foreign social media, and we'll go back to business as usual.
