I interpreted you as it was the parents responsibility to protect their children, ye.
I don't argue for a surveillance state. Authoritarians push authoritarian policies with convinient excuses. I do understand that.
I think there need to be a cultural shift and that involves the collective of parents not indivual families.
Like, my TV installed adtech shovelware over night and my son woke up early and watched it. Sport teams organize on Facebook. The school headmaster wants CCTVs. Door bell cameras are getting more and more common.
We can't fight those things as individuals.
