It's not necessarily that cut and dry. The primary reason for dropping the game was the lack of monetary recognition, but Ancho also struggled continuing the story from a simple creative perspective. Unlike many adult games with a basic structure (find ways for the MC to end up in sexual situations), Fantasy Valley built up a back story and environment around the characters - and they were characters, not just 3D models waiting to moan.
No doubt the lack of income affected the creative side, similar to a basketball team's bad shooting causing their defense to fall off as their confidence weakens. But, Ancho clearly also struggled with the time the story management and art demanded from him. Since few games in this genre offer their creator(s) enough to "quit their day job", it was unlikely FV would relieve him from that time/energy drain.
I'd agree that, considering how much of himself he poured into the project, he would not be pleased with someone else carrying it forward, since he would have already done the hard work of creating the characters and world around them. To see someone else gain money from efforts he fought so mightily to bring to "life" would likely be painful to witness.
However, I am reminded of Stephen King's Dark Tower, a project he once started and then never returned to it until decades later. Perhaps one day...
