Why don't people understand that crowdfunding is not indie shopping? It's a high risk investment. You support projects you believe in (in the religious sense of the word) and if you're lucky, you might get something.
Because what is being offered is neither a debt or equity instrument but a defined good or service, just as with other shopping vebues, and because the kind of detailed financial and other information that would be made available to investors for due diligence with normal high-risk investments is not offered or available for most crowdfunded projects.
