> The MAC address isn't going to 'obviously change';
In the context of these articles (randomizing a MAC address) the address should obviously not be randomized just once but be changed on a regular basis, otherwise it could be followed just like a factory address can.
This is just the main point of the article.

... so changing it on regular basis works. Violent agreement?!
> However, randomised MAC addresses are normally flagged as 'locally-assigned', per the IEEE 802 standard, which could become an indicator of 'something to hide'
This does not really seem to match what Jon wrote above, but it is clearer and does answer my question; thanks.
