Share movie purchases with Apple One

yes this is how

Set up Family Sharing - Apple Support

mind you apple one have nothing really to do with purchases of media from itunes store or family sharing,

apart from the appletv+ streaming service can also be shared using family sharing.

Apple One Individual (smallest tier) consists of Apple TV+, Apple Music, Apple Arcade, iCloud+ 50 GB. Of these, Apple TV+ and Apple Arcade are always shared in Family Sharing. The other two components are individual and not shareable at this tier.

Apple One Family shares all four components with all group members.

Apple One Premier shares all six components with all group members.

Shared subscriptions shares the service, not the usage choices. Those stay tied to each account in individual configuration.

Apple One does not cover buy-items like Store movies. Those are the same for subscribers and non-subscribers.

Purchase sharing can apply to any Family Sharing group (Apple One indifferent), and requires a setting by the Family Sharing organizer to apply it to all group members (you share yours, they share their purchases). It also requires that the organizer pays for all new Apple digital goods and services or the group members (except for each account balance, like store credit). It may also require a credit card payment method for the organizer. If the (adult) group members can’t agree to compensate the organizer amongst themselves, where wanted by the organizer, then this setting maybe shouldn’t be used at all. Purchase sharing only applies to sharing buy-items; subscriptions are not affected.

icloud is also shared had to remove it because the mac and ios stuff of my parents and xwife ate up my icloud storage pretty quick.

I’ll keep that in mind, thanks!
