Unless you're someone who's thrown cash @ the guy, the whole torturing line is pretty dramatic.
Actually, even if you've thrown money at him, that sentence is pretty damn melodramatic lmao (Seriously, "Ordinary, Traditional"?).
We're people here, enjoying a game for free, and we don't know his future plans (female content may be added later for this area, we aren't patrons who can read his Dev Reports etc.)
If the majority of people paying him for his game are voting for MLM content, it is how it is.
There's been plenty of adult themed games that end of focusing in a certain direction (CoC2, TiTS) etc.
While it may suck when game development seems to be going a different way than you would prefer, at the end of the day; you have to know when to move on.
Also, if possible, support the developers who are creating content that you would like to see.
