Wifi equipment has started down a road of anonymization. Linux users have been tinkering with macchanger for a while (though not effectively enough to stop the native MAC address from popping up now and then). Apple made the first big splash when they made MAC randomization standard for scanning mode; Android copied that. Microsoft followed suit with a MAC randomization in more modes. Then the Linux folks finally did it right by building MAC randomization features into Network Manager. The idea, of course, is to keep the original MAC address suppressed.
Stay tuned for more.
