You don't have to be constantly filming your kids, that's optional.
This is a cute spin, but what you're saying is "I like the glasses because I can film people without them knowing" it just happens the people in this case are (mostly) your children.
>> what you're saying is "I like the knives because I can cut things" it just happens the "things" in this case are (mostly) your vegetables.
Again, I'm not saying this out of some bad faith, I just think this argument doesn't work the way you think it does. We actually have no data as to what its most commonly used for, apart from the headlines. Anecdotally, all my friends who have them use it for the exact same reason I do.
