CN authors at least don't give a shit
I know for a fact I've passed a Naruto clone novel before
This. China tends to not give the most blatant of fucks when it comes to any property that isn't on their soil and thus, you get ALOT of extremely blatant ripoffs no one can do anything about as China doesn't obey the rules of anyone else.
I've seen this happen for multiple franchises like F2P MMOs up to the hugely successful franchises.
