The average individual can have no influence on YouTube. So decide for yourself. Is there enough good on it to keep it? Is it a near source of temptation to you or to those who have access to it through you? Has it caused you or those in your care to sin? Are you continually scandalized by it? If the answer is ‘yes’ to all but the first question, delete the app. Get rid of it. People lived, even thrived before YouTube!
If you benefit from it, can be selective without losing your peace of mind, haven’t sinned because of it, and haven’t negatively influenced others, then keep it. I mostly listen to sermons and conferences, watch the occasional docuмentary, listen to music, take classes, use it for practical matters, like learning how to collapse a self-erecting tent, learn a specific craft like sewing, knitting, crocheting, or learn handy household “hacks.” As for YT generated recommendations, I glance over them on occasion, click on if something looks interesting. If it turns out to be a waste of time, offensive, questionable, or just plain stupid, I don’t continue watching. I forget about these sort of junk videos. Most of what’s “Recommended for You” they get wrong. I really only limit myself to sites to which I’ve subscribed.
