As far as I can tell, any decision theory that disagrees with CDT in this case is mistaken. The author (or you) need to sweeten the deal; either the benefits need to be better, or the cost needs to be lower. Typical ways to improve the benefit are to attach status or other goods to the donation- whenever I talk about the Kickstarter projects I back, I make sure to mention that, you know, I backed them.
You missed an opportunity here. ;)
