If the developer isn't doing a good job or completely abandoned the project it could be hardforked and a new donation address could be set up or completely removed. That in combination with the no votes makes it pretty fair in my opinion.
But this no vote does not matter too much. If 24/72 vote no, dev will get 48/72 this round. The rest is deferred to next round. So the next round subtoal will be larger. The total to be donated does not change, it just takes longer to collect the whole lot.
