And you can also sideload apps (only in the EU), change you default navigation app from apple maps (only in the EU), and use more features of the NFC reader (only in the EU).

The code for all of those things is there, but not enabled if for most iOS users. There's a non-zero chance this code is there for Apple to try and convince the EU to let them release a Siri AI, and then just like sideloading have some impossible-to-actually-use alternative path to make the DMA happy.

Apple can hold the AI customers hostage by locking this level of AI integration to their app store, taking a 30% cut of AI subscriptions while at the same time having someone else fix the reputation of their devices' voice assistant for them.

There's profit to be made by offering customers choices here, I'm sure Apple will be ready to scoop up all of those delicious slop dollars.
