Relatively few newly walking babies have peers whose parents allow them to use stairs unattended making them feel socially excluded for not also using stairs unattended.

Ignoring the existence of peer pressure and calling parents lazy is a failing of individuals.

This is not going to get rid of peer pressure. That existed long before kids had phones and it will continue to be a problem with this.

Parents should be there to teach rather than just restrict. Kids will need to learn how to recognize and deal with peer pressure at some point.

Also Apple definitely benefits from peer pressure generally. Their devices are seen as status symbols, the dreaded green bubbles, maybe more. I wouldn't expect them to do anything to actually improve things in this area.
