I don't think this example, however sad, is valid:
- addiction should harm the addicted, not somebody else
- from the article: "The girl, who was born prematurely and weighed 5 pounds (2.25 kilograms), was often fed rotten formula and was beaten when she cried out of hunger, the affidavit said." so what killed this child is not "Internet addiction" but being born to abusive parents...
