Yes, I am aware of that and that's exactly what I was getting at.

The witnesses themselves are not decentralized; they are anything but. You have a maximum of 12 very "central" entities securing the network. And while I believe that the witnesses do not have the same amount of power as, say, EOS delegates have, it is at the very least intellectually dishonest to speak of "decentralized witnesses".

Now, maybe you could actually decentralize a witness, by making it a group of entities, playing merry-go-round or something. I think this has been discussed before.

TL;DR:
Calling a single person a "decentralized witness" is misleading.

I spare us all an inappropriate joke about certain news items and the decentralization of a human being, for obvious reasons.
