Again I'm personally hoping we get a happy ending, and a canon bad ending may actually upset some of the dev's supporters (if they were expecting a happy ending). If they were to withdraw their support, that would be measurable "damage". That said, I think any controversy would be irrelevant if it didn't impact the dev's income.
This game has been going for several years. During that time, the dev has gotten more skilled and presumably invested in better hardware. The first couple of chapters look a little rougher but I think they still hold up well enough.
