The issue with screens is due to the addictive quality of experiences on screens (tuned by highly paid experts to increase "engagement"!) causes more people to turn to their screens than would otherwise be distracted by other things, such as newspapers.
So instead of tolerating your child's soccer game because bringing and reading a newspaper would be a hassle, seem antisocial, and not be that much more interesting, one can just whip out their pocket computer and have some bright colorful beep-boop gamified but ultimately meaningless experiences much more engaging than the game.
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.
Powering through boring material is an important life skill. You can be bored to tears by your boss or your job but you still have to do it.
A person will learn better from an engaging teacher, but someone with no experience learning from dry content will be woefully unprepared for that first experience.
