This is always Strava isn’t it? Was it Finnish security services that leaked the exacti location of the president because some of them wanted to share their runs? Why don’t militaries and security services just ban it?
Strava just happens to be the most popular run tracking app. If they banned it, another would take its place. If anything, they should be working with Strava to create an incognito mode. At this point, the US military should be willing to spend millions of dollars supporting that one feature
It's not the service that should be banned but the hardware that connects to it. No active duty military personell should be using personal devices nor should they be able to install anything on the devices provided for them.
They do ban it. Humans ignore bans. They'd need a comprehensive device restriction - and then they'd somehow have to keep soldiers from keeping a second phone around.
