I agree, and that's one reason I like curated content such as PBS. We had some inappropriate/disturbing "next video" suggestions on YouTube that initially seemed OK at a distance or for the first few minutes that we didn't catch right away. So I wouldn't trust kids using YouTube except if an adult is setting the playlist and watching with them.

Whereas the PBS Kids apps (and Scratch Jr, Kahn Kids, etc) have curated content that I trust. We still limit their screen time and monitor their use by working in the same room, but it's not nearly as risky to let them use it on their own.
