I don't understand. A MAC address is only relevant in a physical
network segment. You simply *must* give a MAC address to hosts on
your segment in order to have networking. But beyond that segment,
there's no meaning to a MAC.
Sure, someone can look it up and find out what kind of NIC or
embedded device you bought. But no, I don't see a "serious privacy
concern" here. Am I missing something, or are you?
