I understand that being over 18 may be sufficient for a person to be responsible. But it would be a much better control feature if you only shared your purchases with family and make your own purchases and the others their own too. Maybe I have credit, and I want to buy an item, or maybe I want to buy it with the orginzer credit. Those two possibilities are more than real. I mean, now there is apple music, with a great family plan, maybe I just want to share that, and not everything with a "relative" grown up, that just turned 18. Or worse, maybe I have a relative that is an adult but he has different capabilities. That person for the fact of being an adult will always be controled on his expenses in the real world, being over 18, but I can't do it on family sharing, though I want to share with him all my purchases. I mean, it's not that difficult to enable, it is much better to give control to the organizer that makes the family group, to invite anyone, controlling their expenses. If I am invited to a family group and maybe I don't like that I cannot use the orginzers credit card without asking, then I don't join. It's that simple. Thank you, hope contitions for family sharing change.
