I'm not a gamer so I don't know much about Zelda, but the sort of hypnotic hold some Youtube/Insta personalities have on kids is astonishing. They will parrot their talking points, talk about them relentlessly with friends and buy whatever they're shilling, be it makeup, game guides, phone skins, what have you.
TV, movies, and games are forms of entertainment. Advertising is a form of manipulation.
Sure, the lines can be blurred, so we do our best to filter out the bad intentions.
Modern advertising seems to become more effective as well. I never anticipated a defense of ads, but I've actually been criticized by visiting relatives for keeping commercials out of reach of our family. We're "out of the loop" now, unable to relate to a joke or situation delivered by commercial. And around holidays and birthdays, we get asked "How do your kids even know what they want without commercials?"
Likewise, it's fine if he wants to watch the videos we've taken of our family, it helps him to remember relatives we don't get to see very often.
Conversely, I have ZERO tolerance for advertising. I am increasingly convinced that marketing is the source of a majority of modern society's ills and I don't want it anywhere near his brain until he's able to properly comprehend its purpose.
