In my opinion Current One Piece is exactly same as Old One Piece, nothing changed
But what is making it less enjoyable than it was before is Weekly Reading, Forum Discussions & Debates, Toxic Fandom, Wrong Expectations (Due to Theories & Power Level Debates), Breaks, Tiresome (The Manga is +1000 Chapters after all) & Early OP will always feel Nostalgic ... etc
All of these eventually lead to the Reader getting tired & annoyed till they feel that One Piece isn't good anymore

On top of that, the humor is gone, One Piece isn't funny anymore
