If you've been watching the documentary of Broken Age's development you'll know that Double Fine is not ripping off the backers. From everything I've seen they've been throwing all they've got into making the game as good as it possibly can be. It hasn't been mismanaged and even though the game is going over the budget from what they had originally planned they are still making a game for a much, much smaller budget than many other games released today. Also, don't forget that a portion of the kickstarter money goes towards filming the documentary (which has been worth my backing the game all on it's own) and Kickstarter tier awards.
In the end, I believe that Double Fine has put a lot of thought into this decision and even though it's not ideal, it's the best decision they could come up with to deliver the best game they could. Sorry but nobody on these forums will be changing my mind on this one.
