No more than 5% of all the people on F95 are patreon subscribers to any adult game developer -- it's probably closer to 1%. 6+ million people with accounts on F95 come here to download for the specific purpose of NOT paying anyone anything. Your argument is moot and ridiculous.
On top of that, over 100 million downloads of the game have been from people playing for free across multiple sites- not the 30k subscribers on DC's patreon. Finally, the game is free for everyone - no one has to or needs to pay a dime to play this game directly from the developer, directly. No one.
Unlike many other adult game developers, DC doesn't paywall his game. He gives his subscribers other perks for their support - which he provides as promised to them. Although I have never subscribed to anyone on any of the platforms, I don't see why people feel the need to deride those who choose to. Oh wait, I do see why, it makes them feel superior in their dreary, meaningless lives.
I recommend everyone forget the game if all they are going to do is whine about "how long the developer is taking." Go play one of the other 16,000+ games available through F95 downloads. Or go play them all - and once you've played all the others, and only then, 40-odd years later, maybe check on this title.
