Doesn't work on phone. Especially if you're on the road. If you're at home and use YouTube on multiple devices, of course you can use a pihole or something.

I have a long commute (which is not very unreasonable). YouTube Premium also lets you download videos on your phone and have it background play. I usually record talks/lectures the previous night before my commute the following day. Has definitely help me keep my sanity!

My kid watches YouTube sometimes and I'm sure she'll appreciate getting this when she was younger so much so that she will naturally develop the aversion to ads when she grows up! :D
