I really believe that this has nothing to do with kids. "For the kids" has made me suspicious of intentions for a long time. It makes it difficult to argue against it because it implies that you're a pedo or are doing something illegal otherwise. You implement general monitoring "for the kids", and then you add some anti piracy stuff to it, then you add some hate group detection, some anti government group detection, etc. Now you have everything you need to get ahead of any danger to the government. If the people can't organize, you can do whatever you want.
