Iirc California had a similar proposal to this. I actually think it’s not a terrible idea at the core. It’s basically an API for parental controls. You set up a device (or account on a device) and say “this is a device for a kid” and that gets used for everything. It actually makes a lot of sense to do something in that direction. Part of the reason people are convinced something needs to be done is because managing parental controls across the different myriad services and apps is a labyrinth that tech savvy parents can barely navigate, and less savvy parents don’t stand a chance.
