Historically there was a problem where user's data was aggregated into a global view. But these days you'd have to follow the user on Strava to get this sort of track.
I suspect that a journalist at Le Monde has a naval buddy on Strava and posted the story.
And why would a Le Monde 'journalist' dox his 'buddy' and expose and thus endanger the ship? Anything for a click?
I'm sure someone in the tech team is getting questioned on this.
> Strava also made it (in 2019) so you'd need at least N samples for it to be visible
Presumably you're talking about the Global Heatmap? This used to be updated only annually. Is it more real-time now?
