And I thought these kind of theories can be based on logical reasoning, but yeah, fans wanting an overpowered main character, despite him turning lame, sounds more plausible.

I think the Will of D idea sugested by Regulus might be a good explanation for Blackbeared's ability to eat more Devil Fruits. The other known characters with a D initial don't use it because of personal reasons or simply because they have no knowledge about it. However, I don't really want it to be so simple like that, even though I can't find any cons regarding it at the moment.
