#2This looks like a fairly significant GDPR breach

#3Oof! Does anyone recommend any tools for protecting against this sort of stuff? I feel like a VPN wouldn’t even be enough here since the MAC address is coming through the headers.

#4Linux lets you reassign your own MAC. There's no reason to use the same one twice in public! :)

I think the full answer is to never trust anything on a page that isn't from the host domain: achievable via the uMatrix plugin. I dont understand why anyone would trust random scripts from a random company (and sometimes just an unnamed cloudfront endpoint).
A less intense version is to use a PiHole or otherwise block bad domains at the DNS level via a regular ad blocker.

#6iPhones randomize the MAC address when connecting to hotspots (on a per-ssid basis, I think?). Other platforms do too (Windows 10 now has an option to do that automatically as well, but I can’t recall if it is enabled by default).

IIRC (this is old and might have been wrong in the first place) iOS randomizes when it’s searching for networks but not when it’s connected to one.

#8Does anyone have a theory on what the "advertisers and trackers" want a MAC address for? If they're using it for anything load bearing, it seems like there is an interesting CCC talk lurking here for anyone who wants to visit that airport with a few hundred dollars worth of devices and stuff a few tens of million spoofed MAC addresses into the system.

#9The problem with constantly shuffling MAC addresses is that they are used for device authentication on corporate/school/university networks. Does anyone know of a utility that generates MAC addresses as a hash of the SSID?

Since MAC address ranges are allocated to certain manufacturers, it is a simple way to track your device type. Additionally, all MAC addresses are unique so it is the easiest way to match/combine your data from different trackers.
