My main thing is I want to be able to opt in or out of various filters. I don’t mind if my kids want to listen to music that has swear words, but I don’t want them watching videos where they give horribly sexist pickup artist advice.
This isn’t just about what I feel is age appropriate, either. It is also about what I know about my kids.
My 10 year old hates scary things, and she gets completely freaked out when they show scary movie previews. I would like to be able to block those for her. On the other hand, my 7 year old is obsessed with scary things and I don’t mind if he plays zombie video games.
