That's like saying that people saying that The Akatsuki Leader could have been Yondaime Hokage who faked his death because of the similarity in hair style had credit to their theory.
Regardless, it did have enough meaning that Kishi tried to quash those theories by having Obito grow his hair out during the Uchiha Massacre, in order to look a bit more like Madara to Itachi.
