> Those who are surprised that you have to pay for access to an ABI have obviously never had to pay for their compilers from their software vendors (the price for the HP-UX garbage compiler was eye wateringly high). But that doesn't seem to be the case, as Apple hasn't monetized Xcode and the iOS SDK libraries differently since the DMA came up. Apple can charge for the SDK and all that it entails, but they can't charge for apps getting to run on users' iOS copies, as that's not something IP law contemplates. What happens when a fully FOSS iOS dev environment comes out, like the way you can compile Windows binaries on Linux right now? What would Apple be charging for then?
