The intent was for people to be able to freely sideload apps.
Also, it is in the law. There was a specific part where it said that gatekeepers cannot sidestep the law via contractual terms, or something similar to that.
But once again, I am more that happy to come back to you when the EU regulators take action against Apple, to force them to comply.
Will you admit that you are wrong if action is taken by the EU regulators against Apple?
The problem is not access to the SDK, the problem is that Apple is locking down their platform to competitors. They can't sell apps or content without giving a commission to the "gate keeper" Apple.
Epic is not one of the biggest device manufacturers. And Microsoft is definitively not locking out third party developers from Windows. Everyone can just sell Windows applications without paying Microsoft a dime. Windows is even fully open to PWAs, with the Edge browser from Microsoft or any other third party browser.
But I am happy to come back to you when the EU takes action though!
Anti-trust laws are perfectly legal. We can make and enforce laws that force Apple to change, just like laws exist in all parts of the world.
