Your rights to do what, exactly?
To take a personal risk in backing an unknown and inexperienced individual on a labor of love? One in which they got in way over their head, and are probably doing everything they can while swimming with the sharks?
Crowdfunding is not a pre-order. You crowdfund completely nonexistent products in the hope that they come to fruition and you get to enjoy them at a (large) fraction of their potential cost. You're an investor, not a customer. An investor with very little say in the outcome of a product, and one who's chosen to take a risk on something.
If someone else popped up and looked semi-capable of producing what Earl promised to be, I'd back it again. I want one of these and nobody else seems willing to try and make it. I took a chance, looks like it didn't pan out, but that's life. If the risk is unacceptable to you, wait until products hit the shelves, or are at least in pre-production mode and there's a physical product.
