Journalist or, more likely, EU press release office not very knowledgeable on the semiconductor industry choosing to mention the three largest countries by population in the headline, and the rest in a list embedded in the article. Journalist at Reuters probably just took the official press release and edited the grammar/wording a bit. I agree that the selection should probably be Germany, France, Netherlands, Italy if looking at the relative importance in semiconductors, but probably choosing by country population is a standard thing they do to avoid complaints.
