Sorry, but it doesn't. Real choice for consumers is paying and downloading a third party app from the developer's website. Real choice is third parties developing and distributing their own apps on their platform of choice while paying the corresponding IP to the owner of the development kit, hardware and OS and not be obliged to host on ANY app store their work. Many here say, I don't wanna be binded to Apple's payment system. That's good, but don't fall in the trap that chains yourself to another gatekeeper. Legislate to leave the gate open and let the developers pay their dues, and the IP owners receive their revenue and pay their taxes. What's so complex about that? Why over-legislate?
Not sure why you lead with disagreeing - to me it sounds like we're in agreement.
The DMA doesn't require apps be distributed through a marketplace. They can be made available through their own website. It's Apple that did not want to give that option.
