the leaders of these companies don'tlet their kids use it.
If you know what the platform is capable of, if you seen how the sausage is made, you're probably not using it.
People are also a little naive in not seeing that these platforms aren't just bad for children, they are bad for adults as well. I'm not oppose to not "selling" them to children, but we also need to label correctly for adults and have rules like those for alcohol, tobakko and gambling, so no or limited advertising. Scrub the public spaces of Facebook logos.
I personally stopped using Facebook because it was annoying me with useless doom and aggressive comments of people on stupid topics. If it would have showed me only cat pictures (like Instagrams does) or reasonable stuff (news, etc.) I would have continued using it.
Lets admit it, in same vein trump is a symptom of current US society, the approach and effects of social networks we allow them to be is a result of how lazy and thus addicted people got. On top of many of the parents doing exactly the same, then don't expect miracles.
One thing that I don't understand - even here, some folks call that sociopathic amoral piece of shit 'zuck' and treat his empire like some sort of semi-charity. When I attacked facebook company in the past, there was always a lot of defense (look at this open sourced stuff, look at that... which I presume came from either direct employees or clueless stock holders). People are people, deeply flawed and often weak without willingness to admit it to themselves.
