The EU could recognize it as a strategic security issue to not have the most advanced chip fabs located in a geographical sphere of influence that is not always aligned with their interests. They would work with TSMC in particular because they're the most advanced. The strategic side of things is slightly less of a concern for them if TSMC bring capacity online in the US since they're mostly on good terms, but it's still not great for one of the world's largest economies to not have this sort of capability inside its borders.
