I was thinking, backer may have lots of difficulty to ask for compensation if the thing will never exist or being sent, but.. What about people that preorder it on the website?
This is clearly a commercial there, and people are BUYING goods, so, they are covered by the normal laws, unlike backers which are basically only "money giver with a potential gift"
I wonder how many people have bough their product on the website, after the indiegogo campaign...
