Earlier quoted context omitted.
The DMA imposes FRAND obligations on gatekeepers and free interoperability requirements ("interoperability" here meaning literally everything from using the installation APIs to install apps from the web to being able to call all OS APIs for free on your app. That's why Apple's "Core Technology Fee" is screwed)
Do you know which sections of the DMA address this? Genuinely asking because I’d like to read from the source here.
> The gatekeeper shall allow providers of services and providers of hardware, free of charge, effective interoperability with, and access for the purposes of interoperability to, the same hardware and software features accessed or controlled via the operating system or virtual assistant listed in the designation decision pursuant to Article 3(9) as are available to services or hardware provided by the gatekeeper. Furthermore, the gatekeeper shall allow business users and alternative providers of services provided together with, or in support of, core platform services, free of charge, effective interoperability with, and access for the purposes of interoperability to, the same operating system, hardware or software features, regardless of whether those features are part of the operating system, as are available to, or used by, that gatekeeper when providing such services.
