They don’t. That is why regulation is necessary.

Just like how expecting people to recycle was bad policy.

Though I wouldn’t be opposed to there being statutory regulations against parents whose kids get addicted to these applications and end up self-deleting or causing harm to others, not unlike how we’re seeing the state start to go after parents who fail to secure their guns. But just trusting parents to parent isn’t an option anymore. There’s simply too much evidence of the harm these applications cause.
