Well now Elon Musk is consdiering to take Twitter out of the EU because of the investigation in compliance. It has to do with the new rules created in August called the Digital Services Act (DSA).

I think Elon Musk just is upset with EU watching his moves. I do not really think he will remove it from EU. https://www.reuters.com/technology/musk-considers-removing-x-platform-europe-over-eu-law-insider-2023-10-18/
