Those are literally dumb fucks who never touched anything more than a manga in their life. I believe on Reddit you'd find literal retards who'd dare to call OP a literature
It's hard to base anything on sales since One Piece is the most shoved down everyone's throat manga in Japan.
They are milking OP every chance they have and treat it like the golden egg.
500 mil copies sold. 80% is purely in Japan. I mean c'mon.
The downfall of One Piece is one of the worst downfalls because this manga had so much potential and at some point in the past Oda was really decent for manga standards. Unfortunately, he was surrounded by the wrong people ( editors ) and I doubt he will change on his own.
His editors: Shueisha spy ( probably making sure to milk Oda even for the cost of his health declining ), furry pedo, hentai addict.
I mean c'mon.
I remember Oda even said that "He'd love some critical input from his inner circle".
Which literally translates to "I am surrounded by agenda driven dick riders not people".
