Excerpt from this article:
As a group of scientists from different countries and academic fields with research expertise and experience in screen time, child development and evidence-based policy, we are deeply concerned by the underlying message of this letter. In our opinion, we need quality research and evidence to support these claims and inform any policy discussion. While we agree that the wellbeing of children is a crucial issue and that the impact of screen-based lifestyles demands serious investigation, the message that many parents will hear is that screens are inherently harmful. This is simply not supported by solid research and evidence.
