Re: Think of it as a donation, not a purchase
Crowdfunding is great.
More correctly: Crowdfunding is great when the backer gets what they consider acceptable for what they invested.
It's also great when backers don't get what they expected but they understood the risks of their investment.
It's not so great when backers don't understand what they are getting into and that's compounded by those facilitating crowdfunding not being entirely transparent and ruthlessly honest about what they are getting into.
