People wanted to help Oni but he doesnt want it so its his fault.
Actually, no, it is not. If developer has a made up working routine he is comfortable with, he should not force himself to move to the teamwork, where he has to also supervise other people and do management stuff instead of developing. It is not a commercial product on sale, there is no contract between patrons and developer like "we will give you n dollars, and you will hire the guy to code, and will shorten the developing time to x months per update". Oni's rate of developing is stable, guaranteed and he is providing exactly what he is offering, holding his side of the bargain.
The difference between Vilelab and Oni is that Vilelab is promising a great game with shittone of content and progress, while Oni says "I produce this kind of content of this rate, support me if you like it. Your support will not make it faster".
I am comfortable with this rate of developing and quality of content, hense why I am paying 5/month to keep it running. He had not promised me anything he had not delivered.
