First of all, The game has various routes. According to your choice, the blackmail story has a completely different output. So you are not forced to endure jamsines sufferings, you can set her free.
Second, you are free to support a project or not. You can of course express your wishes, criticize and make suggestions for improvement. But you do not have a right to have them heard.
But with all understanding, what you say/write here is outrageous. If you are familiar with the rules of patreons and other of these platforms, you should know that you will then support developers in their vision. The tension is on their vision!
But what you give of yourself here means something like:
"Kindly do what I want, everything else is crap, or there will be no money". This is contrary to the rules of patreons, that you agreed to when you joined there. We usually know that outrageous behavior from so-called NTR haters. And already there this is not okay. A developer is not the "fulfillment slave" of your wishes. And if that really suits your character, it really isn't a shame about your "bucks".
Think about it.
