Children who have been under constant surveillance might not have any great concern about their government merely continuing the practice.

[Secret Agent Man]

The fact you are not considering is that sometimes it can be right for someone to be under surveillance, and in other cases surveillance is something that can be abused and turned into a tool to oppress people.

The kids in question aren't being oppressed and parents have more than one legitimate reasons for possibly considering this.
