Note: Maps and location information depend on data collection services provided by third parties. These services are subject to change and may not be available in all geographic areas, resulting in inaccurate or incomplete maps or location information.
That’s irrelevant. If the databases are the source of the problem and if the problem is that they’re inaccurate the onus is on them to ensure the correctness of the data so one guy and his family are not getting harassed at their home because of Apple’s software.
The interaction is end-to-end encrypted, and Apple cannot see the location of any offline device or reporting device. When your device participates in the Find My network, it can both be located by the network and anonymously help locate other missing devices.
