I read a CNN Money article which said suspect suicide (with confirmation from coronar coming later). If I am incorrect I will edit my post and apologise.
I'm not disputing that it was suicide. I'm pointing out that your claim as to why he committed suicide -- an "inability to deliver on the kickstarted campaign" -- is pure conjecture.
You don't know why he chose to end his life -- nobody does -- and making up stories about it is irresponsible. Even those closest to him have competing explanations, e.g. http://www.businessweek.com/articles/2012-05-10/on-diasporas....
