Exactly. It's a well-armoured safe door on a safe with no sides.

100% stopping kids in voice chat isn't the goal. Stopping kids from accidentality joining voice chat is.

So nothing is stopping them from purposefully getting a chat activated account, that's the point.

The law itself disagrees. It's quite explicit that the point is to not allow kids into chat rooms at all without parental consent. It does not mention anything about preventing kids from accidentally joining chat just that they are not the ones able to provide consent to allow chat.

Is your argument that the law specifically has language interpreting its goal?

Can you quote it please, because I find that surprising.

Voice chat without parental approval is less likely to happen if the device is in public space in the residence.

This is true independent of the law.

I've made fake accounts for my kids where I lied about their age, in order to bypass certain restrictions. That's how screwed up our legislation is in this area.
