I agree completely, it's not really about the toys (tools) it's about the parenting. Any toy can be overused/abused/misused, leading to issues. A good parent interacts/guides/limits their childs toy use and doesn't depend on the toy itself to raise their kids.
I would guess that the vast majority of people who are critical and linking to studies, either don't have children or don't realize that they are recommendations and guidelines to be applied by parents as they judge fit.
I'm also sure that the same Associations and Societies recommend 30-60 minutes a day of tablet use, many of these same people would criticize parents for not letting their kids have 20 hours of use time. Which, because its *more*, would somehow make them Super-Awesome Baby Einsteins.
