Hey meta, watch my kids for me.
I raised my kids with devices. They hate social media for the most part, and participate in it begrudgingly.
All meta had to do to avoid this was run the occasional "you have been doom scrolling for 20 minutes, do you know what your kid is doing on social media" ad's and the problem would have been solved (for them). But parents would have to own their own social media addiction issues - Im reminded again of the old "I learned it by watching you" ad...
The earlier papers on the risk here date back to 2012. You can go all the way back to myspace and the Megan Meier case (2006) to know how things were going to turn out for kids, online, unattended.
Great meta pays the fine.
In 20 years this crop of kids will, as an outcome of therapy, go "no contact" with their parents, who refuse to own up to doing a bad job raising them with unfettered access to social media.
