I think you have already been underestimating the quality of resources available in French, Russian, German, and others, that do not exist in English. Just as a single example, the math section of the French Wikipedia was distinctly superior to the English one when I was in college (2012).

France's #1 export product us culture so I am not at all surprised. They also invest lots of money in this. French cultural centeres abroad are more funded and in many ways better than any other embassy operation.
