Google makes money, so they are happy to look away.I personally think they know this about kids being addicted to YouTube too. I see so so so many kids in my life spend hours on end watching Minecraft videos and the likes. I get it, "the parents"!!! However if a child's parents don't have the time to police their kids internet usage, they fall victim to this pray very, very easily.
I have some friends who don't have a lot of money and they both work together running a cafe. The kids basically have to look after themselves because the parents are just too busy working. The kids just spend practically all their free time watching this shit.
Google cannot be so naive.
