This is a storm in a teacup. Many of the AI features are being delayed anyway, and I'm sure Apple are perfectly capable of figuring out how make them DMA compliant. They deal with regulatory and legal issues all the time - it's part of normal business.
If for some reason Apple can't figure it out, it will simply make them look further behind on AI, and their customers will blame them, not the EU. The bottom line is whether Apple can deliver features to their customers, and moaning about having to comply the EU regulations won't get them anywhere. They'll get it done, just like they did with USB-C.
If AI features turn out to be genuinely useful, and Apple can't / won't deliver them, it will simply drive customers towards phones like the Samsung Galaxy. And if they're not, who cares anyway.
