         | At one time I guessed that too, but I've heard navy people
         | explain that it's actually pretty effective. Imagine saying
         | 'pretty hard to hide in North America from a satellite' - it's
         | actually not hard because the area is so large; there aren't
         | live images of the entire area and someone needs to examine
         | them. Oceans are an order of magnitude larger.
         | 
         | A significant element of security for naval ships is hiding in
         | the ocean. US aircraft carrier planes have a ~500 mi effective
         | radius without refueling; even if you see a plane, all you know
         | is that the ship might be in a ~3,142 square mile area. And
         | remember that to target them, you need a precise target and the
         | ships tend to be moving.
         | 
         | With ML image recognition at least some of that security is
         | lost. Also, the Mediterranean is smaller than the oceans, but
         | the precision issue applies. And we might guess that countries
         | keep critical areas under constant surveillance - e.g., I doubt
         | anything sails near the Taiwan Strait without many countries
         | having a live picture.

         |

               | 
               | I was also part of a cycling club that did a regular
               | "club run" on a Sunday. 5-15 of us all doing the same
               | route. It was good for club morale for us all to upload
               | our rides to help show how popular it was and encourage
               | other club members to come along. They could see that we
               | weren't going at a silly pace and that we stopped
               | regularly to regroup as we had riders of all abilities
               | and speeds riding with us.
               | 
               | But then I also helped out with my kids running club at
               | school, taking a bunch of 7-11 year old's on a 20 minute
               | jog/run (depending on how quick they were) around the
               | local area. This _absolutely_ should not appear on Strava
               | (public or not). The running club wasn 't a secret
               | (everyone at the school knew since they had the option of
               | letting their kid do it) but that's a whole world of
               | difference from having it public on Strava showing the
               | usual start time, the various routes we used to take,
               | where we stopped, etc. Privacy zones can help hide the
               | start/end but that wouldn't help hide everything.
               | 
               | We just made sure that all of the parents who helped out
               | knew that we shouldn't even record it with their
               | smartwatch. I just used to create a manual entry of
               | "Morning run" with approximate distance and time. That
               | was good enough for my training stats.
               | 
               | There's no one privacy setting that handles all of this.
               | Whatever setting you use relies on me to manually adjust
               | the activities that don't fit that setting. The problem
               | is that humans are fallible, so remembering to make it
               | private or hide the location data isn't entirely
               | reliable. You're also at the mercy of Strava (or
               | whatever) not doing something stupid and accidentally
               | making private data visible due to some bug, glitch or
