If the EU finds apple guilty of "systematic" non-compliance, which will happen if they "continue their shenanigans for every judgement", then the DMA doesn't call for a fine. It calls for a TikTok style forced sale. Apple could be ordered to sell the iPhone to another company or face an outright ban in the EU.
Of course that's assuming the EU has the balls to actually enforce their own laws knowing full well the transatlantic political consequences.
