I constantly reinforce two things with my high school son:

1. How ludicrous zero tolerance policies are.

2. How scrupulously he should avoid violating them.

I will never feel truly relaxed until he graduates and leaves the long arm of the school district.

This reads more like a warning to inform parents about its existence. Nowhere does it say not to let their children use it, it merely says "If your child has access to this particular application, please consider having a conversation about watching, creating and potentially sharing videos." It seems like quite a reasonable message, really.
