I feel like this idea is good in the planning stages but fails to realize some of the operational constraints. Amazon currently has drone delivery in only a few metropolitan areas. In part it is due to regulation and in other part it has to do with cost. It's not a profitable business model even in the most population dense cities. The whole point of giving people access to these contraceptives is because they are incredibly rural and as a result cant afford the cost. It would be incredibly expensive to transport these goods via drone. A better way may be to use a helicopter to drop supplies or in fact, find ways in the supply chain to send these contraceptives in bulk and resupply infrequently.
I think this is a great idea to provide useful health and sexual education in the form of a mobile app and game. However, what about areas that do not have access to these technologies, or better yet what if their parents do not wish for them to access these topics. Speaking from personal experience in America, Sex is a topic that is mentioned sparingly and is almost taboo. Even the idea of a game spreading sex (even if it is education) would be controversial.
