That if anything tells the dominant influence apple have that they can hypothetically do that kind of damage.As things stand right now, I do see some problem for smaller US publishers, though. They could fear the ire of Apple outside the EU. It would be a nasty move by Apple, but they could make life really difficult for publishers who still need to be in Apple's App Store to reach customers outside the EU. Large corporations of the caliber like Google, Meta and Microsoft on the other hand can probably deal with this situation.
Hopefully such an action must be illegal in the U.S. right?
