This Chika issue only exists because of the devs on mistake, AVNs have their own genres, when a dev tags a game in a certain way players will expect a certain type of content, they will play and sometimes even support a dev based on what is said, if the devs change their way or somehow start adding content that is clashing with the core tags he mentioned at the beggining of development, players will feel they were lied to, and as such will lash out.
Anyone that has being around the AVN world could have expected this type of reaction from their players.
Pale Carnations is a great example in this regard, you dont see this type of reaction there and prostitution is all around it, the difference is that players always knew what they would get by playing it. The dev was clear and honest about its content from the start.
Now this is just my opinion, but to say you have no respect for players because of their reaction, to a mistake you made is honestly embarrassing. Vanilla and Prostitution dont match its as simple as that, if the game had been tagged properly no one would have reacted this way.
