Calling John Alexander Cuza's name "defamation" is overreactive hyperbole.  Both names appear in the lead of his article, and if "invented names" are defamation, then millions upon millions of people are "defaming" Jesus Christ by calling him such! He's really "Yehoshua" in Aramaic, not "Iesu" in Greek, or "Jesus" in English or Spanish.  Now, I don't think you would be able to make that case.  

Let's see...Charlemagne is "Carolus Magnus", "Karolus Magnus" or "Charles the Great," George III of the United Kingdom is "King George III" (birth name  "George William Frederick").  In short, trying to claim that there aren't different names for people in different languages or areas is one of the biggest cases of tilting at windmills since Don Quixote (Sorry, I meant El ingenioso hidalgo don Quijote de la Mancha).

Additionally, you are also claiming, in essence, that any wiki not in the native language of the subject is defamatory of the subject by its very existence because it's an "invented name".  For example, George Washington is ja:ジョージ・ワシントン,("Jouji Washinton").  So you claim an entire language group is defamatory because their alphabet is different?  Really?

Now, everything else aside, what I think this really is is some sort of Romanian ultra-nationalism on your part, and that's not appropriate either.  I say "ultra" because you're having a fit over not content, but the spelling of a name calling it "defamatory" and "invented".  That's very overreactionary, and if you don't like the connotations of the label, don't engage in behavior that will label you as such.
