As the language is finalized behind closed doors, most tech companies and their lobbyists are resigned to passage of the so-called Digital Markets Act. Other provisions in the DMA are aimed at the likes of Inc. and Google parent Alphabet Inc.

The DMA’s most existential threat to Apple comes with a provision that would allow software makers access to the iPhone—through so-called sideloading—outside of the rules and payment scheme of Apple’s App Store. One recent draft of the DMA, overwhelmingly approved in December by a 642-8 European Parliament vote, included sideloading.

The first thing to come to mind is Apple’s Dutch dating solution. To require app makers open their books and pay Apple 27% tribute. They feel, down to their very bone, that they deserve a portion of every transaction that passes through an iPhone.
