I don't have kids -- what's wrong with this feature?

It's a vague ick.

Both parent and child are now mediating their experience through technology with the parent blaring recognizable intellectual property at the child to psychologically manipulate them into a better photo.

I mean, I remember having a guy squeak a rubber ducky at me when we took family photos... that part isn't new. What difference does it make that it's recognizable IP? It's Snoopy. Kids like Snoopy.
