A few answers say “they aren’t private by design,” but don’t really go into the “why.” There’s the obvious “it’s an electronic tracking device, duh” reason, but there’s also a more nuanced reason:
Airtags are able to be picked up almost anywhere because they connect to the nearest bluetooth-enabled Apple device, and then send location info across the internet to you. Without this functionality (the ability of any and every Apple device to locate it), they wouldn’t have any way to send their location back to the owner.
Your best “privacy respecting” alternatives are something that uses meshtastic (and hoping there’s enough repeaters near you), something that uses cellular data and GPS (which is about as privacy-respecting as Airtags are), or just a key finder/beeper (which only works within a small radius)







Because privacy is a spectrum, and it makes a good stepping off point for the people that still use text messages and social media chat clients to stay in touch. I can’t convince half of my nerd friends to leave Discord for literally anything less shit, but I can convince even my tech-averse mother to use Signal instead of FaceTime.
