Why? I rather pay Apple wich I love than Netflix wich I’m neutral about. Actually I will quit it if a good alternative comes around (wich I doubt, haha).
Same goes for Audible...
Maybe Netflix will add an option that will allow you again to sign up on ios and just pay an extra 15% on top of your subscription. So 7.99 + 15% directly to apple, just as a service for people how like to pay apple
