There was already a campaign - humanetech.com started by no suprise a former Googler a while back.
Through internal studies, they already knew quite a few years ago that Google engineers where as likely as to get addicted and waste time on cat videos, the kardashians and whatever else as much as the people the platforms end up hooking. Those results produced some internal 'what about my kids' outrage.
What they then discovered is deaddicting ppl is much more complicated and takes a whole lot longer than getting them to turn into screen touching addicts. It was so complicated not to mention the opposite of what generated rev that it got quietly shelved and ppl left No big diff between Google and Big Tobacco in this regard.
What you are seeing today is them dusting off the cobwebs on that project as the unintended social and psychological consequences are finally taking a serious unignorable toll.
I don't see Google or Facebook contributing to the solution. They will play the same game Exxon Shell Philip Morris et al play. And that game remains empire defense.
It's up to you to keep your kids safe.
