It depends on what you consider "value". Apple would argue the distribution through the App Store is part of the value chain. I think the real issue here is that Apple demands 30% always. 30% might be the "distribution value" for small indie devs, but it probably decreases once the developer is big enough and their products are well known (Epic/Fortnite, Spotify). Then it becomes just a tax that indeed skews the price-elasticity curve.
