We have mandates for all kinds of things, like movie ratings etc. I think it’s appropriate here. It just makes it easy.
I don’t understand the pushback from tech companies either; all OSes already have a kiosk mode (incl the major Linux DEs). Should be very low effort to implement.
The concern is that OSes which don't implement the feature will be outlawed.
Movie ratings don't outlaw movies and actually provides a good framework: instead of mandating that OSes implement this, publish a client-side filter spec that OS devs can choose to implement. And if they implement it, their OS gets a label like "PG-capable". Then make it illegal for minors to possess a non-PG-capable device.
Movie ratings are not mandatory, at least not in free countries. MPAA ratings like “R” and “PG” are a voluntary classification system and films are free to opt out, though many theater chains may be less likely to show your film. But small theaters and streaming platforms don’t usually care.
Authoritarian states like China and the UK do require classification/certification of films before release. Imagine requiring a painter to have their paintings reviewed by the state before exhibition!
