Pretty insane for you to believe that a foreign country from afar could produce mapping data with the same degree of accuracy, detail and realtime freshness as a local provider on the ground. Of course there's military value in protecting mapping data from foreign adversaries, at the very least it adds a a time delay and some uncertainty to the data. It also probably makes it harder for some unsophisticated terrorist to strap a consumer GPS to a stock drone and accurately hit a target.
