It seems like business in general doesn't want to do anything for child safety. For example, imagine if the school asks that parents buy a laptop for their children. But ordinary laptops do not have "school mode" which would allow children only use it for studying and not for visiting inappropriate sites or use messengers.
Or, imagine if parents want to buy a smartphone so that the child can always call them. But again, even on iPhones you cannot allow children to use a messenger but restrict to whom children can talk to.
Or take websites. Currently as far as I am aware no web sites provide HTTP headers with information about age restrictions.
To summarize:
- laptop and smartphone manufacturers do not want to invest in creating safe environment for children
- website and app owners do not want to invest into this either
