Well it was expected to be abandoned. It was clear that the team favored the NTR route, and apparently the writer they brought on (if I recall correctly, it's been a year or two) definitely favored the NTR/sharing because the 'harem' route went stupid, with all the women exploding once they found out about each other.
They 'claimed' that the routes were equal, but they weren't as noted. Would not be surprised if they got tired of trying to fake being equal in their content for the two routes when the game started as a NTR fest and they tried to expand the other route to get more supporters.
