In these discussions, the focus seems to be on the cost to Apple for providing App Store as a service (billing, fraud prevention, tax compliance, etc.). However, presumably there is a reasonable argument to make that developers should compensate Apple for creating iOS itself as a platform. There are many platform capabilities developers argue for as a fundamental right. Spotify has said Apple must make Siri extensible for voice control, others have wanted SPI to be API. All this work is meaningful investment, both financial and technical. Are there proposals for a more incentive aligned business model for Apple as a platform provider? Would it make sense for Apple to, e.g., charge a percentage of all of Tile's hardware sales? After all, Apple dedicates resources to maintain the location and bluetooth APIs Tile depends on. Is it sufficient to say all these benefits must be capitalized into the cost of an iPhone purchase? But what about the customer who's overpaying for Tile's theoretical support who never uses the product itself? Maybe a better business model would lead to a world where there is less speculation ahead of WWDC: the developer's needs and Apple's finances are so aligned that we can guarantee the new support they're ready to announce!
