Again, where is my Nintendo store on my Xbox
Again, the issue is that Apple hasn't allowed any iOS app store alternatives (outside the EU) while there have been alternative places for buying Sony, Microsoft and Nintendo games.
Outside of the law the EU created just for Apple, it isn’t anticompetitive or illegal to have a closed platform you charge access to.
They didn't "create it" just for Apple. All gatekeepers have to follow DMA laws. In the critical mobile OS market, that includes Android and iOS and potentially others who choose to enter. Just because Apple may have been the worst "offender" regarding restricting app store competition/choice for developers and consumers doesn't mean laws were made for or only apply to them. Google/Android, for example, also had to make adjustments.
If Apple allowed alternative app store competition for iOS as they do for macOS, they wouldn't be facing these types of issues. Issues that took too long to start to be addressed.
Do you know the devs pay Sony, Mirocosoft and Nintendo the same fee no matter where their game is sold, doesn't matter it is sold at Game Stop or on console store.
It can matter as far as overall selling costs as commissions paid can vary depending on where a game is sold.
