Yep.
Read some article recently about how Published Manga has been on a very bad downward trend for years. You have a few "golden" manga like JJK or KNY that come and go and sell big in short bursts, but Jump hasn't found decent manga that's effectively been able to replace Naruto to match the longevity of One Piece.
Then you look at One Piece and it gets pretty scary for the industry as a whole because when it's gone, what will fill the gap for the 1+ million copies it sells every 4 months?
People like to unironically shit on OP sales in this forum. Out of everything, it's the one thing that shouldn't be criticized, especially considering it's basically keeping Weekly Jump afloat. Not sure what will happen after it's gone, I guess a trend to digital mostly.
