This article is not about restricting the use of mobile devices or parenting, it's about regulating the software industry. Parents don't want their kids to be exposed constantly to advertising on their day-to-day lives, or pressured into buying things all the time.
The European Union is doing a good job regulating businesses, however, Apple is doing a lousy job regulating their own ads and payment systems. And this is because the AppStore makes $60 billion a year thanks to ads and subscriptions.
In my opinion, Apple and the AppStore should be regulated more by the European Union.
