Daisy Greenwell and Joe Ryrie, parents from Totnes, spent years watching their children grow up alongside smartphones, feeling powerless against the pull of endless scrolling and algorithmic feeds—until now. In a sweeping policy shift, the UK government will ban social media use for anyone under 16 starting next spring, joining Australia in drawing a hard line against the digital forces reshaping childhood. Backed by 90% of parents in a recent public consultation, the ban targets platforms like TikTok, Instagram, Snapchat, Facebook, and YouTube, though messaging apps such as WhatsApp and Signal will remain accessible. The move follows a stark warning from the Academy of Medical Royal Colleges, which placed concerns over social media and smartphone use on par with public health threats like smoking and seatbelt nonuse, citing children’s exposure to “hateful, addictive and grossly distressing content” online.

This isn’t just a regulatory change—it’s a cultural reset. The ban marks a turning point in how societies value childhood, placing wellbeing over engagement metrics. The Smartphone Free Childhood Movement, co-founded by Greenwell and Ryrie, hailed the decision as a victory for grassroots advocacy. “For years, parents have been fighting a losing battle against some of the most powerful companies in the world,” said Ryrie. “Today feels like a turning point.” The policy reflects growing global momentum: Australia implemented a similar ban in December, France has approved a ban for under-15s, and countries like Denmark and New Zealand are considering their own versions. Even tech leaders are feeling the pressure—Meta and YouTube were found liable in March by a Los Angeles jury for designing addictive products that harmed a young user, a verdict likened to Big Tobacco’s legal reckoning.

Critics caution that bans alone won’t fix systemic issues. Chris Sherwood of the NSPCC warned the policy could “punish teenagers for tech platforms’ failures,” while others fear children may migrate to less regulated corners of the internet. Yet the core message is clear: childhood should not be shaped by Silicon Valley’s profit motives. As UK technology secretary Liz Kendall stated, “Tech companies have had countless opportunities to keep children safe, yet they have failed to act.” With this ban, power is shifting—from tech giants back to families. And as momentum builds worldwide, one truth becomes harder to ignore: the emotional lives of children are not for sale.
