> engineers why they work for companies that track and addict kids.

If you think addictive games are bad, then we can go ahead and cast a moral judgement ib parents too. Parents know that games are addictive. Why are they letting their own kids play addictive games?

As far as engineers go, it is possible that they did made the game addictive specifically for <13 years old. It just happens that parents of <13 year olds let their kids play, and they are getting addicted.
