There are a number of places i go during the workday where fitbits are prohibited. And most of any business trip is spent in no-go spaces.
Wonder how the company insurer will deal with those rules...
So there are fitbit free zones? Please elaborate.
Not allowing devices that track your location and report that data to an unsecured server, or to a system that is not locked down by, and in the control of, the military, seems like a very sensible requirement for secure military facilities.
There was a situation in (IIRC) Iraq, where US airforce personnel took some team photos of themselves with their newly delivered aircraft at the dispersal point, and posted them online.
What they didn't know (or didn't think of) was that modern phone cameras attach EXIF data to photos, which includes the GPS coordinates where the picture was taken - so you can sort your photo album by location, which is pretty neat.
Or, if you are an Iraqi insurgent, you can use the EXIF data from online snaps, plus Google Maps, to precisely target an aircraft dispersal point in a large airfield with well aimed mortar fire, and take out a brand new jet fighter worth millions of dollars. Which is rather less neat, at least in the opinion of the Pentagon.
Information is a weapon of war. The military prefer not to hand that weapon to their enemies by allowing personnel to broadcast their every movement to the entire Internet.
It's one thing for the Russians and Chinese to know that US nuclear missiles are somewhere on a base that covers half of North Dakota. It's quite another thing to give them the exact location of each warhead to three metre accuracy - which could easily be gleaned from fitbit data, if the personnel at that base were permitted to wear them.
