I think it's irrational. "Screen time" is today's Dungeons and Dragons and heavy metal. People are doing things differently today than I did at that age, therefore it's bad and needs to be limited.
Moreover, maybe both sides are right? Maybe you need heavy "screen interaction" to be successful in this world and maybe too much time is being consumed by screens rather than physically interacting with the world. Maybe there is a balance that isn't close to being struck by most.
Maybe I would like my future children (if I have them) to interpret the world largely through their own eyes rather than a clickbait interpretation manufactured to get more money.
Schadenfreude on that one.
