What I am not happy with is a lack of control over the homepage and recommendations. I would really like to be able to easily block channels from ever showing up, but you can only sort of do this if you click "don't recommend this channel anymore" from the homepage. But you can't do this if a video shows up recommended from another video. And overall, it just feels like they are spending so much effort trying to get me to watch the next video instead of enjoy the one I am trying to watch.
For my kids, I came up with an ad hoc policy where they can watch from the homepage / recs on weekends but during the week have to stick to a personal playlist they can only add videos to on the weekends. This removes the algorithmically driven addictive nature of YouTube and unsurprisingly they end up moderating their use of Youtube within their alotted screen time much better. It distinguishes between, "I want to watch this" and "I want to pull the slot machine lever." But I would be a lot happier if I could better curate access to content for my kids too. Youtube Kids sucks, it ends up filtering out a bunch of interesting stuff like carpentry and nature content that hasn't been marked "for kids" in favor of videos of kids shopping for toys and stuff.
