Changing the underlying find my network to break this would be challenging if not impossible while keeping the privacy protections in place. Apple can’t identify devices sending data to find my, and doesn’t log requests. Short of changes that would break compatibility with older devices it should be relatively stable.

OpenHaystack has been doing this for a few years now and Apple has made no efforts to restrict it.

I’ve been using FakeTag[0] and OpenHaystack[1] coupled with a vibration sensor to notify me when various things happen around my house. Inspired by this [2] article. It’s worked flawlessly for ~2 years.

You're correct in saying that it would be challenging for them to overhaul the entire network, but this library directly makes API calls to Apple's servers to request location reports. So while the tags would likely keep working, they could totally block the library or your account if they really wanted to.

So what you're saying is that a decent firewall could still inspect the traffic, or the patterns thereof.

Also, this doesn't make any sense, as if Apple doesn't know which AirTag belongs to who, Find My would be very useless; and law enforcement would be furious.

Airtags are associated with your apple ID for safety, but when you make a request for the location from Find My it doesn’t include any information about which airtag you’re asking about; just a CSPRNG-incremented public key that changes every 15 minutes. The location data itself is not available to Apple.

Here is Apple’s docs on how they prevent themselves from inspecting traffic on Fmi: https://support.apple.com/guide/security/find-my-security-se...
