This is no different than any other developer I pledged to. I set a certain max price I am willing to pay for and after that I stop pledging if they do not meet RoI to me. It really is not rocket science. I normally let out a little rage monkey and then just be on my way as I think I earned it. NergalsNest was a great example of this.
Do I want other people to not pay, no. Do I wish people had more common sense like me, yes. The developers are not entitled to my money.
