This is really bad news...
I my opinion this is the very best developer in the NTR world. I love all the games he made. Even Lost in paradise, Exploring the big apple and pineapple express are in my top ten. The games are long enough to go through the story. I think they have the perfect length. The big games either are 3/4 slow burning and only 1/4 interesting or all in from the start then a lot of scenes with nothing to add and the shorters just pass in five minutes and ten minutes later you completely forgot about the game existence.
Just stop guessing what really happened. It's useless and ig the dev wasn't clear enough it's because he didn't want to be public.
I think he's wrong about the F95 leaking. No software succeeded avoiding the free version. Windows easily cracked with q keygen or copies like tiny win11, games are always cracked even the newest consoles can be chipped to accept games not from allowed channel. The apps are modded with plus versions also streaming are easily cracked. F95 is not a problem in fact is the biggest help.
If the game is only in Patreon nobody ever is going to know about the existence and if fortuitously someone cross the dev site no way he become supporter without trying the game. The top successful devs always share with F95 and most of them even are active members.
The real problem is the devs are atoms. At least q bunch of geeks spending the day in the basement typing in a PC and wanking.
They should create a 'Club', a Union or some kind of association to improve. Like fighting a Patreon's (or whoever) politics, getting sponsors, agreements and other interest like moving Renpy in some way, etc.
There are a plenty of ways to make it much more profitable than the supporters.
