This episode explores some of the risks that monitoring and censoring children can have on their development and also the effect it can have on the parents themselves.
There are actually people who consider a story like Minority Report not as a cautionary tale but rather as a challenge along the lines of "They just did it wrong in fiction, we can do it better in reality!".
Just like I'm pretty sure there are quite a few parents out there who would watch that BM episode and go "I'd totally put such an implant into my child but I'd do xyz different!".
The moral sounds to me more like: if you keep your innocent child locked away from the world, you might just create a cure for blindness.
