That seems like a pretty big assumption. From what i understand there already exists deployment of wifi hot spots to track people (both for advertising purposes and for spying purposes) to the extent that phone providers started radomizing MAC addresses.

Cisco’s meraki has that built into their devices. I run meraki in my home and have it enabled and it’s pretty powerful. If you see a wifi network, it most certainly can track you and if it’s not a residential network, I assume it is.

This is why I don’t like the automatically re-enabling wifi setting on iOS.

Yes you can still turn it “really off” in settings (until the phone reboots again) and yes I put a shortcut on my home screen to turn wifi/bluetooth all the way off in one click, but probably barely anyone is doing those things because it’s inconvenient/they don’t know/they forget.
