I'm saying it doesn't really seem to be a Strava problem, and that the problem on the military side likely already has a solution in place.

It's a platform problem. The cross-availability of information on let's say ... Google Android. They can use a microphone, wifi signal analysis, and other techniques that make your GPS coordination data moot. What's getting more complex is the data itself, and how it be sorted and moved around the need for actual location data. That's why I think the "disable GPS / Location" actions in Android (and macOS) needs to be more granular. When we say "don't track me" .. it means ... on everything and protect the information from software in silos. It goes against the grain of security vs. usability .. but its gonna happen by will of the people.
