It's like the argument about students starting out the window, or at a ceiling, during a lesson. The answer is not to remove the windows, nor is "scolding the ape" a good solution. The real answer is to compete on engagement, and make the lesson more interesting than what's outside the window.
Likewise, the way to have more people engaged in a sporting event is to make the game more engaging. But then more people yell obscenities at the referee.
In the end, all of this "screen time" nonsense is just a dumb way for some people to feel better than other people.
