Just a tip for those of you that do cave to pressure and go with the paid premium option. or already have one but dont want to pay for more accounts or a family account.
You can set up channels or brand accounts as sub-accounts on a premium subscription and they will act like separate accounts with the advantages of premium, so if you have a large family and don’t want to pay for the full family subscription (which only has 5 slots anyway) you can set up a few sub-accounts that each get their own subscriptions, recommendations, settings and all have the premium features.
So if you want to make a premium account for a parent or child, you can do that with one single subscription if you can take the caveat of them being brand accounts rather than fully their own thing.
This works on things like Android TV or Google TV, but you need to log into the main account then switch to a sub account in the app, however, there is no authentication to switch between channel accounts this way, so it’s really only useable for families only. I use this at home to run 4 separate nvidia shield youtube apps with their own subscriptions and recommendations on one single premium payment.
I expect they will change how that works in the future to remove the loophole, probably by charging for channel accounts or having it locked behind some kind of overpriced professional usage tier, but for now, it might be a good option for some.
