A trivial amount of legislation can fix that. Law reads: ISPs must implement implement parental blocks by default, exceptions may only be made on a per-device basis. Parental controls must also be enabled on public wifi. Easy as that. It doesn't matter how lazy you are, actively going and turning something off is more effort than not.
>ISPs must implement implement parental blocks by default
This is already the case in the UK. We discovered another sad fact. Parents will suddenly develop the technical literacy to turn parental controls off because it's inconveniencing them, but won't bother to fine grain the control to make it safe for their children.
