Yes, that turned up a week or so ago on the german forum. The consensus, after much discussion, is that it may well be the result of some business arrangement between Piaggio and Changjiang. If it isn't, I dare say Piaggio is currently disscussing legal action with their lawyers.
Incidentally, that article seem to be poorly researched. Firstly, the thing is called "Deffender", double-f for whatever reason. In the film at the top of the article behind Rany's link on can see the double-f very breifly on the wall behind the bike. Secondly, the quoted power figures don't correspond to other reports that I've seen. For instance:
from here
https://www.motorradonline.de/enduro/changjiang-v-750-deffender-gespann-guzzi/
and Motorradonline is generally very well researched.
Given the similarity of those figures to the "old" V7 motor with the heron heads, I could imagine it really is a licensed copy of that motor. Moto Guzzi has retired it, after all.
