Age restriction on cigarettes and alcohol is not for kids that are not parented but to prevent companies abusing kids to make more profit wich is why I say selling of internet connected devices and internet connection should be done to adults only. But don’t force me to give companies all my personal data.
The problem with that is that vulnerability will be found and used. Since it’s connected to the internet it will be exposed to attackers and could be infected with botnet viruses/tools and used to attack other computer/services.
