Some Google Photos videos in ‘Takeout’ backups were sent to strangers last November
With Google Takeout, you can download your data from Google apps as a backup or for use with another service. Unfortunately, a brief issue with the tool last November saw your videos in Google Photos possibly get exported to strangers' archives.
How does this even happen? Too bad companies like this have armies of lawyers and obtuse terms of service to hide behind - since software is a special little butterfly that isn't held to the same standards as any other product we use - so nobody will ever be held accountable for this.
