DMA has shown us that Apple will do the absolute minimum to comply with changes like this. The fact that Apple is asserting it's power over an app distributed on a third-party store is a whole new example of legal changes not actually giving us what we want.

There's also the location issue. DMA forced Apple to make some changes but only in the EU. Apple is willing to do the work to only comply in regions where they have to. What happens if your country decides that Apple isn't doing anything wrong?

If this is something you care about then you should not buy an iPhone. First change the rules and then buy one when they comply.
