Afaik, the EU hasn't done anything "with" or "to" Apple Intelligence. Apple just keeps shooting themselves in the foot intentionally and then blames the EU for it, writing paragraphs about how hurt they are while mentioning at the very end, in one sentence, that the same features are unavailable in China.

EU has forced Apple to use USB-C for everything earlier than they planned by a few years, and fined them for uncompetitive practices like the ones Epic Games shed light on in US courts.
