Wait, I'm dumb. It's not a mesh network. I misinterpreted "crowdsourced" here:
It saves the location data end-to-end encrypted in the cloud from which the devices of the owner can read and decrypt it. In a mesh network, the devices themselves would relay the information.
Kind of funny that I originally thought that's how it works even though I also thought:
It also probably saves to the cloud the Bluetooth identifiers of all the devices in your vicinity that are pinging for Bluetooth signal (if it doesn’t already). They wouldn’t state that, but technically very possible/likely given it’s Google.
Even some privacy advocate who is using a pair of headphones and a dumb mp3 player can be located in such a scenario, for the simple fact that they have paired those headphones previously with their phone. Even if they left their phone at home. Given that people don’t share their waxy bluetooth earbuds with one another, therefore there’s a 97% chance they were also there with you. Chain surveillance attribution, on steroids.

Sounds like we are in for a rude awakening of side channels in privacy.

George Alhosry, who owns the Kwik Market & Deli on Roxford, said the store’s Wi-Fi was down much of Sunday. It’s unclear whether that was connected to the heist. But Wi-Fi jammers have become a common tool of theft gangs during their burglaries of homes in Southern California because they knock out many security cameras that could capture video or stills of them or their vehicles.
pretty embarrassing if your security cameras get knocked out by jammers, lol
