  • The problem is that GPS signals are weak, and generally need a line of sight to the sky. Phones don’t rely on GPS alone, but also get location data by triangulating base stations and/or querying databases of WiFi SSIDs over the internet. And AirTags don’t contain either a GPS receiver or an internet connection: they’re just simple, low-power Bluetooth beacons which send an encrypted ID to any nearby iPhones, which add their locations and forward it to Apple.

    Basically, all the smarts are in Apple’s infrastructure (including the numerous privately-owned devices running Apple’s location services). Replicating this without a network of roving receivers is a nonstarter.









  • No ActivityPub-based services are really private. There is no mechanism for end-to-end encryption, access-listed posts, or even true DMs. ActivityPub is intended as a microblogging-style publishing service with interaction built in, with privacy not being in the spec’s scope.

    Maybe some day they’ll retrofit privacy to the protocol, but that would involve reengineering it to handle key management and end-to-end encryption, which would be a hard problem.
