Your suggestion essentially shifts the concept of a 'family' in the context of Apple's family sharing to that of a 'cooperative' of 6 adults. This idea fundamentally alters the premise of the family plan from a tool designed to help families manage and share digital purchases together, under a unified account for simplicity and security, to a system aimed at maximizing cost savings for any group of 6 people. In effect, it restructures the family plan into a mechanism where each purchase essentially grants 6 access keys to content.
This change alters how digital goods are valued and sold on Apple's platform, impacting the economics for developers and content creators. It moves away from the intended use of supporting genuine family units with shared access to content, towards a model that significantly undercuts the value of digital products. Such a model offers immediate savings for users but also leads to broader implications for content pricing, availability, and the sustainability of the ecosystem supporting creators and developers.
