The subtitle says it's not just the screens and if you read as far as the second paragraph she writes "screens surely play a large part in this". So let's not jump straight to conspiracy theories. It's possible that someone who write children's literature for a living is concerned and curious about the causes and isn't just acting as a corporate mouthpiece.

In recent years (since The Atlantic has been owned by Jobs) they've published articles like "The iPhone isn't Cool", "Have Smartphones Destroyed a Generation?" (answer: yes), "How Your Laptop Ruined Your Life", "I Won’t Buy My Teenagers Smartphones", and "The Dangerous Experiment on Teen Girls".

I don't know if Jobs has any editorial influence (and I doubt she does), but the magazine isn't some underhanded pro-screen propaganda machine.

I thought the Jobs' were always open about how they didn't allow their kids to use smartphones or tablets until they were teenagers.
