Intent.
When your parent put sugar in a cake, they you to enjoy the cake for you own enjoyment. They will dose the cake, and make you experience the cake in this context.
Kinder wants you to enjoy it so you buy it again. The goal is not the enjoyment but the reaction after it. Dosing the sugar, the other ingredient, the context you will consume it and the so on are going to be completely different.
When you hear "Ride of the Valkyries" being played in apocalypse now, you don't hear the voice of the director suggesting "now you should feel this particular way, because I said so". You just enjoy the craft.
Some movies and series now, it feels like the way they put music, cuts, etc. are just cheap plots designed by engineers to get something out of you.
You can't feel the desire of creating and sharing something, rather you are given a product designed to specs.
