Do a better job of parenting. Have some self discipline.
There are so many products in this world that take advantage of our biology. The iPhone is just one. And it's currently being obsessed over by media outlets. What about all the processed foods making people fat and unhealthy? What about Starbucks selling addictive drugs on every corner and getting away with it? Same with Coca-Cola, why is adding addictive chemicals to a soda that is sold to everyone including children okay? What about television? All of these TV shows coming out are designed to hook you in. Walking my dog every night, I can see everyone just sitting in front of their televisions, wasting time.
If you are going to force a company to help people ween themselves from addiction, don't be a hypocrite. You have your own addictions and vices, what makes yours more valid than someone else's. If we are going to make products provide tools to limit their own use, lets do that with all of the addictive products out there, and not single out one company because it's trendy to not be on your phone.
