I already don't see ads and don't subscribe, but I legitimately get $12/month of good from YouTube. I'd be willing to pay that for the service they make available. None of the other streaming services available are as useful to me.

However, right now it's hard for Google to data-mine me. Getting YouTube Premium means linking my identity to YouTube activity, and makes it easier for Google to build their profile of me. I don't want that. If Google were to say that this means no logging, no data-mining of YouTube Premium customers, I'd be a lot more amenable to subscribing.
