If I may give my opinion... I think some people are forgetting that this was never a pure harem story, it has some clear corruption/degradation elements and it was being pointed out that some stuff could be quite outside that typical "pure harem story", still I do agree that it would be great that developers could express since minute one any more or less controversial fetish that may added at any point.
Related to the critics of waste of resources that some of you did point out, I will have to say that I have yet to see a game in which someone doesn't ask about x scene and why does it exist, it may be anal sex, a footjob or any act a bit out of the purely ordinary, so in the end should the game stick only to the most basic stuff that all people agree that should be included?, if you do you are the most generic game ever.
But that's about it, I can only recommend that you people chill a bit, I understand that something you hate got added but it is optional and you can still play the game without issue.
