Unity: We have to charge for every install because we only see totals. Also Unity: We can tell which install is which, so you won't be overcharged.

I think this is rather about checking the MAC "from the inside", as a program running on the computer. This will work on a PC, as I think neither Windows or Linux systems restrict reading the MAC addresses of network interfaces and such, by default at least. On phones, I don't know. But the point is that now the "attacker" is not on the wifi network you want to connect to, but inside your computer, and wifi mac randomization is worthless. Not just that they might have access to the original MAC of the wifi interface, what about the MAC of other interfaces like the cellular data interface or ethernet (over USB, when its supported), and then theres tons of other info too by which they can identify the device.

Well, if your mac address changes every time you connect to a different network, Unity would be detecting and billing for a lot of false positives, so it would be a bad method to identify unique devices.
