BREAKING NEWS: Local man on pirate porn website says he is not going to support game developer with money
I believe there's nothing wrong with a stance like this.
There's a whole culture of 'sampling' a product using torrent sites or a site like this and only then you make a decision whether or not to buy it.
As for porn gaming goes, I had only one mistake with the Innocent Witches - I supported them for 4 months, 1$ per month. That was like 4 years ago. If I'd still supporting them given that things aren't going anywhere with this game - you can imagine there are a whole lot of better things to spend your money on.
On the other hand there's a whole culture of making 'promising' projects which turn to be 'sample' games made to earn money fast. Like those Early Access ones on Steam which got abandoned soon after (not all of them of course). Or even better - make a sample game for Patreon and then pretend that you working on it. For years. It's not a big deal for a person to spend some 1-5$ on a game could be released any day.
Imagine you'd spend on every game you liked here on this site and NONE of them will be released. Personally I went through the " wow, I like this game. I think they're close to release a full version of it in a couple years, then I'll buy it for my collection and basically to support these artist" process several times.
Also I believe if someone declares that he won't buy a game, it's not just some angry talk. It is a matter that a developer should've listen to. If they give a damn of course.
