I don't think this discussion can go anywhere because we have brutally different views on this.
First off, as a supporter, and this is true for a lot of supporters out there, if the dev stops making the content I want in the first place, that's as good as if he stopped making contnet in general. I will not keep supporting. And if we're talking about someone whose main shtick was the things Patreon now deems wrong, I don't see many sticking with them. I would be willing to support them off patreon, I would be willing to put up with how many tricks they need to pull to circumvent Patreon's rules (like, for example, releasing a version of the game without the forbidden content on Patreon and then elsewhere giving out a patch that puts the content back in. Some people who sell h-games on steam do this, for crying out loud, it is NOT something that would likely get them in trouble). I am not willing with sticking with them if they drop the content I support them for because they are too afraid of losing their income. Money in a crowdfunding environment comes from their fanbase. They should not disregard the fanbase in order to try staying in a platform that doesn't want them. The fact people encourage them to do this is fucking unbelievable to me.
If making games represents most of their income, these people should have been looking for alternatives to stop depending on Patreon long ago. Just like Youtube, relying on a third party platform who has no compromise with you always keeping the rules unchanging is stupid. This is not the first time Patreon has made very clear they are against erotic games, first they made them impossible to find through search, now they are enforcing rules about not publicly disclosing the pornographic nature of the content on the front page and policing what you can and can't do porn about. If you really think it will stop there, and that the devs changing to appease Patreon you make them stop, you are a fool. They'll keep taking and taking until they successfully wiped out this disgusting porn problem that keeps embarassing them in front of their partners. They are forcing the devs to stop or to drop the content they were supposedly passionate about and that got them a fanbase little by little, because they know people like you will always look for a compromise and think things won't get worse. Devs who are going along with it and supporters who keep encouraging it are being the useful idiots Patreon needs right now.
I don't know what the people trying to defend and say that they should adapt to whatever the tought police wants them to are into, but I guarantee you, you are coming next in their list of problematic things to get rid off.
Now lastly, about how crowdfunding works. Yes, you are not buying content but supporting the creator. But it baffles me how people will do whatever mental gymnastics and semantic hair-splitting necessary to relieve the creator of any kind of responsability towards his patrons. Especially when we're talking about the model people use for porn games, where updates come gradually, building up to a full game some day. It's just contradictory to argue that the people aren't supporting the dev because they want him to keep working in the production of that game. Just like you support an artist so they can keep doing art. You are helping him with monetary incentive so he keeps doing something that otherwise they would need to stop doing because they'd need to earn that money in another way. While the platform does give them the freedom to change and drop projects whenever he wants, that is just a cheap move after being supported by those people's money for so long. I really can't call people tryint to shut down anyone pointing this out and saying the devs shouldn't have obligations, that you are paying for the (incomplete) contnet that already exists and shouldn't hope for anything more, and other similar accusations, anything but intelectual dishonesty.
