That is not what I asked. We already know what the result of such a poll would be - more Paul + Jessica, more incest (with Alia too, but to a lesser degree). That is what people have been asking for the most since the very beginning. Not just on here.
Imagine a different situation. YOU have created a game. Let's say for example, you don't like rape all that much and you don't understand the appeal. But you're not super bothered by it meither, as long as it doesn't go too far. And you include a little bit of rape in the beginning of your game, because it makes sense in the story. But - oh no! You happen to live in a parallell universe, where rape is a super popular fetish and people are asking you to include more and ever more gratuitous rape scenes in the game.
Would you cave to popular demand or would you continue to develop the game how you like it? Or would you just move on to a different project?
Regarding the milking Dune for $$$, I can't rule it out. I can't look into Balsamique's head. But I know that many artists are fickle, and they don't like working on a single project for too long. So they jump between different projects or at least they have side projects, that they work on from time to time. Balsa seems to be like that. He started Vega Hunters before BtD (the first one) was even finished and then he worked on both of them. And then he had a number of side projects, most of which never went anywhere. One of those side projects grew into Horror in Hongdae. And now BtD is one of several side projects that he works on when he isn't in the mood for HiH.
I have never seen any arrogance from him. He has for the most part simply ignored all the various requests that have to do with incest. Every once in a while he used to explain that he's uncomfortable with the subject and again every once in while he included some incest content despite of that. I would accept the argument, that he wasn't firm enough and strung people along (possibly for $$$). But I'd rather have a little incest content in my favourite artstyle and with my favourite characters rather than none, so I'm not complaining.
Sorry, I jumped a little ahead and didn't answer you.
If I was in Balsamique's shoes, I would probably have done something like this:
"I am not comfortable with this or this, don't ask it will not be in this game, if that's what you want look elsewhere. I don't care what you offer, I am not doing it."
and put that sentence or something similar near the top of the thread or before the description of the game. The problem that Balsamique has created is that it was in the game from the start as far as i remember and I do not recall any comments on his patreon where he said he did not like incest. Does he have a discord where he mentioned that? Maybe on another forum? It is also possible that he may have put it somewhere here and I missed it.
By "arrogance" I was referring to when he asked for ideas for the game, my response as well as others had to do with Jessica and Paul. I get that some people might not be into that, but when his response was to do only Jessica content and ask again, then add Jessica and Paul content, later asking again, where content with only Jessica was added I took that as arrogant. My point of view is that he didn't mind it in the past, and when asked randomly would tease Jessica and Paul content in hopes of either keeping his subscribers or getting more subscribers.
Combine that with the amount of responses to BTD versus his other games, an argument could be made that BTD is his most popular game that generates more revenue versus others.
I could be completely wrong here and this could be more so due to my supporting devs in games over the years that failed and either didn't listen to their subscribers or marked their game as abandoned, only to come back with another game do so again.
