Completely agree. As soon as he get's a decent amount of Subscribestar Patrons, he will switch and then... Well, either support two versions or kill Patreon. Depends very much on his own preferences. He is the developer of this world. Which mean, he is it's god, just as GRRM is the god of Game of Thrones or I am the god of the books, that I wrote.
But, even a god does have external influence. Remember that story about the gods that disappeared, because nobody wanted to believe in them anymore? Same thing. He has to listen to Patreon and fans, Subscribestar and fans and so on...
