like honestly why are you expecting such a generic name to not be used in a slightly different fashion by someone else
The fact that he's claiming he's the original, however, is the problem here. Sure, someone could have the exact same name as me, as long as he isn't trying to claim that he's the real one if I was the first to claim the name.
It's like someone trying to make a company named "Appel", selling electronics, yet they practically copied the name of "Apple".
