Uncesored is showing the image before censoring.
Decensoring is turning a censored image into something that's not (like redrawing dicks)
Just a guess but uncensored usually means some official version is there without lightsabers. Like English or Taiwanese official translations that don't have censored panels. There the dicks etc are drawn by the original artist.
Whereas decensored means it was uncensored BY the scan group, as in the group has someone to draw the dicks, so it's not wholly the original artist's work. Ig they call it decensored so as not to be confused with officials' uncensored.
Decensored, Shouldnt it be uncensored?
