Your stated good use cases can easily be performed after/outside of classes. And I would say in this day and age should be part of assignments/homework/studying in high school level education to guide and educate young people in filtering, identifying and assessing source materials better. But that’s asking a lot from teachers, who are not experts at this, either.
I don’t see how any of this discussion relates to funding though.
