I have literally never, ever seen this complaint for a porn game even once in my entire life. Not once. Maybe it is my lack of time spent looking at feedback (as generally looking at other people's opinions on a third party's projects are kind of irrelevant to me anyway), but I reckon it doesn't really happen.
Also, what planet do you live on? With Steam and GOG and whatnot, the indie gaming scene (which includes a lot of point-and-click adventures) is literally in a golden age, and besides that, porn games in general get much more money (especially money that goes directly in the pockets of the people putting in the effort to making them) than the people involved in the development of regular games, which includes regular indie games that don't include the extra enticing option of pornographic content (and, trust me, there is no easier way to get people to give you money for a minimum amount of effort than adding porn to it), yet those still keep getting made, sometimes to the outright monetary detriment of the developers. Some people just like to do what they do and are fine with appealing to smaller demographics in general.
At the end of the day, whether MagicNuts deserve more remuneration for the game or not is a separate issue, but I don't think the project is starving of monetary compensation (admittedly, I guess this depends on where the developers live and how their living costs are, and if they are struggling, then I'll rescind most of what I've said in this post) and I can promise you that the people that come to this forum or find out about What a Legend from somewhere else and/or stumble upon their Patreon are definitely (and I mean this to apply nigh-universally) not looking for a CoD or a Fortnite or to shoot people. Nobody ties the fun and test of skill of a shooter game to their horniness, unless they are in such an insignificant sect of psychopathy that nobody needs to (or should) cater to them anyway.
