I'm going to assume that it's because it really isn't all that important. The military is looking to avoid headlines like "Strava heat maps reveal military base layouts" but they don't really care if the base layouts are revealed. Back when this controversy was first stirred up it seemed unlikely that anything sensitive was really exposed. Other comments in this thread indicate that the military is perfectly capable of restricting the use of personal electronic devices when they care about it. This seems like a case of the public demanding "something must be done" and the military responding with "okay, we did something".
