The grandparent post was wondering what the issue is, and my post described what IMHO is the main potential issue.
You have your opinion on to what degree this might be a problematic instance of cultural appropriation, and I have my opinion (which I haven't stated).
But the point is that the opinion that matters is that of Iroquois people and other descendants and (cultural) inheritants of the person whose name is being used. (Not that they are obliged to have an opinion on this, or to speak with a single voice on this matter.)
