You can make a similar list for Latin though; the Romance languages are (by definition) descended from it; that's Spanish, French, Italian and Portugese, and English and German are heavily influenced by it. That's a significant majority of the score of the top ten languages from the article, so you can argue that by their standards Latin is more significant, even though it's no longer really a living language in its own right.
Good point; I thought the article missed out on analysis about indirect influence by a language through influencing neighbouring languages. Would've been nice have read about Latin's influence on other languages rather than have it being a mere footnote.
