My wife and I pay $15/month for a family plan Play Music + ad free YouTube. How can Google not be making money on this, assuming a reasonable number of customers.

I am a happy customer of both Apple and Google but if Apple continues to come through with quality integrated services, I can see myself just living in Apple’s ‘walled garden’ in the future if they also keep supporting privacy.
