This reminds me of what happened with Strava's global heatmap many years ago, that exposed military bases and where staff moved most frequently.
Strava at the time was high aggressively told they were at fault for "leaking" this information. But this is a problem more so with staff clearly using Garmin, Fitbits, Apple watches, mobile phones etc to log their activity and upload it to publicly available sites.
Strava also excluded the GPS activities from the heatmap where users marked the activity as private or opted out for data sharing.
