Side loading did not fail to create competition, but even if it did, it's a philosophical thing - you should be allowed to do what you want with your device after you buy it, within moral capacity and civil law of course.Then they're failing miserably. To be clear, I have no problem regulating the smartphone market or Apple specifically. I just think there are parts of the DMA that make product design choices that do nothing to fix the problem while creating new problems. For example, side loading and third-party app stores already failed to generate competition on Android after more than a decade.
What are the problems that developer and consumers are actually having that should be addressed?
Commissions? Then limit commissions, especially in areas like music where Apple competes.
Apple not approving certain types of apps? Form an appeals board that can weigh whether they should be approved.
Not enough platform diversity? End Google's anticompetitive agreements with all of its competitors.
Criticizing the DMA is and will always be valid. I understand we are in an Apple forum here, but it doesn't mean EU's solution is perfect.
