Just FYI, you can have ad free, tracking free YouTube content if download YouTube Vanced. You don't have to root your phone, either. Can play videos in the background and a lot of cool features. I'm not 100% sure on their privacy stances, but must be better than Google.
Ha! Fair point. I haven't done the research on Vanced privacy, so yeah...using Google as the bar is about as low as you can go.
