My problem with YT Kids is that the business model of YouTube is inherently incompatible with children and law. Here in Sweden advertising targeted at children is banned[1]. YouTube Kids is more or less all product placement, influencer "reviews" and sponsored content. Why would a child need thousands of videos? I would curate and download a library of videos.
