Now, two of the biggest investors on Wall Street have asked Apple to study the health effects of its products and to make it easier for parents to limit their children’s use of iPhones and iPads. […] Jana, an activist hedge fund, wrote its letter with Calstrs, the California State Teachers’ Retirement System, which manages the pensions of California’s public-school teachers. When such investors pressure companies to change their behavior, it is typically with the goal of lifting a sagging stock price. In this case, Jana and Calstrs said they were trying to raise awareness about an issue they cared deeply about, adding that if Apple was proactive about making changes, it could help the business.This open letter is getting a lot of attention, but to me, the way to limit your kids’ access to devices is simply, well, to limit access to devices. I’m sure iOS’s parental controls could be improved (and in a statement, Apple claims they have plans to do so), but more granular parental controls in iOS are no substitute for being a good, involved parent.
