Apple has zero leverage here. First, they are a foreign company so there is no local sympathy like in the Epic case. Secondly, the EU is already pissed off with Apple, hence the DMA. Thirdly, even if Apple doesn’t care what the EU thinks, their shareholders surely do, since the EU has the capacity to inflict huge financial damage on Apple, via fines, import bans and/or much more punitive regulations.
Fuck around, find out.
