It's okay that it doesn't match your experience but it's also a case that you shouldn't extrapolate your expectations and experience onto others.

There's plenty of overworked, stressed or ignorant parents who really wish they could care or they don't at all.

"should have enough digital literacy" doesn't survive reality check - reportedly 12-26% adults in the UK (% depending on the country) is reported to have very poor/lack of basic literacy skills. 25% approximately are functionally illiterate.

Reportedly (I'm not an American), 36 million of US adults are functionally illiterate; 43% cannot read a simple job application; 41% of low-income households lack digital literacy skills.

Those are only two prominent examples. More developed countries (especially in Europe) will fare better, many countries will fare much worse.

I think your heart is in the right place but the reality stays in disagreement.
