you do know they might actually have personal issues right
Somehow I actually believe that people creating porn games might have an above average tendency to suffer from personal issues.
Nevertheless, probably totally normal that many creators lose their motivation over time. It starts with enthusiasm and probably in a moment of enough free time, but after a while things become boring, repetitive, and feel more and more like work. It is like when you play a computer game. Most likely after some time you stop playing it and you do something else.
Of course people who love the creation, like to have more and more and for free. And when the content does not come, they are angry, because "That guy gets like 1000$ per month and nothing is coming". They believe that the amount of money the authors get, should bind them to deliver content. But this is just not how it works. Most of the time, the angry people are no patreons themself. The money comes from people who thing different about their pledges as they should according to the angry people.
Also I see quite often authors engaging heavily with the community, even here at f95, but over the time they leave, pull back and reduce their communication to their own filter bubble in their discord or patreon chats. More often followed by even being less present there. Of course there are many many other examples, but it is some stronger trend among those authors that for some reasons lose interest and time for their project. I believe that behavior is pushed also by the angry people here, who demand things.
So: Porn game authors are often people with personal issues and hence predisposed to stronger suffer from a spiral down due to their fan base expectation not being matched. Nevertheless, there exist some ultra dumbass fucktards authors that rub their dick on the money piles from even more stupid fan boys. Furthermore, a simple minded group of selfish permanent angry assholes without empathy for the actual challenge of writing a game are losing their mind over the situation and are raging blindly against everything in this forum. And those shit discussions pop up again and again all over the forum, since nobody actually knows what is going on with the authors and hence, it is believe against believe, like century old religions fighting over meaningless stuff.
