You don't need to read the news every day, let alone every hour of the day.
It's an addiction to the way news is currently produced.
It's entirely reasonable to spend an evening a week reading up on tech news. It's not reasonable to have a compulsion to check the news whenever you have a down minute.
I'm guilty of that myself, I'm currently writing this while a program compiles but I wouldn't wish this on a developing mind.
Besides, there are other places where news and the internet is available, why shouldn't places legislate away having that 24/7 on smartphones during school.
