I don't like the screen time generalization either.
What about watching a tv show with a parent explaining? What about trying a videogame with a controller on an actual game console, experiencing remote controlling something in a screen (Spoiler alert: amazing results, I have a video with my daughter shocked at age 2).
Smartphones used as a babysitter with a f2p game is probably garbage time
