Crowdfunding is by far not the worst offender in all of these fees. What about event tickets? Even http://www.dnalounge.com/ http://www.dnalounge.com/ charges outrageous "service" fees when buying tickets online. For NYE, the ticket price is 50$, service fee is another 10$ -- that's some 20% commission! (And not at all unique to NYE, either.)
