MIlitary Intelligence - A contradiction in terms.
This is an app where users share their activity. They choose what data to place in the public domain so this is no revelation especially that this information and concern was raised over three years ago when police warned that users were leading thieves to their garden sheds, where they stored their expensive bicycles by not setting up privacy zones as many people also made their make and model of bike public.
This by its own admission, a storm in a teacup given the Google Earth pictures. When there are Strava heat maps which tally with the secret blanked out areas Google Earth we can say that there is anything other than clickbait. Anybody that does not understand they are carrying around a tracking device in their pocket whether they have Strava installed, or their GPS even turned on must have been living in a cave for the last decade at least.
Good practice in ICT for me has always been 'opt in' as the default. Fundamentally this is what people are doing when they accept T&Cs when they install an application. But who reads T&Cs or user manuals? Certainly not anyone who signs up as cannon fodder.
