Hmm, where we live (western Switzerland), this is the default among basically all parents we know. Locals, immigrants, doesn't matter. Not every single thing in same way as article, but cca same ideas and approach. Simply reasonable.

Any digital screen is simply too intense stimulus for those little minds and leads to passivity. Human mind is wired internally to create habits -> addictions naturally. And most stuff in those screens is highly addictive, even without going into the topic of brain and soul cancer that all social platforms are in one way or another (and many here are even proud of contributing, then folks wonder how trump can happen repeatedly... the trail in US is long but ie reality shows are one of the stepping stones - stuff mostly marginal here). Also time spent on screen is the time spent alone, no social interaction. Not the best idea for developing mind.

Its true that our circles are mostly university-educated folks but not only. Expecting different behavior in families of say car mechanics or prison guard on average. We know one local farmer family and they do same as we do.
