@PepsiVisa because the editor is a dick, maybe he hates futa and say "you fuckers made me review this shit, well here's something to stop sending me futa to edit"
In regards to the double censor. As I understand it, usually printed releases have just bars but digital distributors require mosaic censoring. DLsite and probably other digital distribution sites state this requirement if you look under submitting works to them. I believe printed version can get away with just the bars and less censorship because the artist has the printer and publisher to back them us if it was ever brought to court for a lack of censorship. Whereas, the digital versions the artist is on their own and digital distributors do not take responsibility for it in order to reduce the risk of charges ever being brought against them. This made sense when they were small and just starting out. I don't think they need to have this requirement anymore but they keep it anyway because that's just the way they have always done business. The double censorship comes from adding this mosaic requirement from the printed versions.
