In my view, "children" are used here, because the topic is school apps. On the other hand, one thing special about children is that we have specific laws to protect the privacy of their school records, namely FERPA. This also provides a potentially useful attack vector that the rest of us don't necessarily enjoy. This problem might lend itself to a class action FERPA lawsuit against the school districts that have released the information.

I'm going to assume without being a lawyer, that sending out school data is a violation of Federal law.
