The point is that crowdsupply vets projects that they are at a stage where a lot of it is actually just finishing design and manufacturing, or at least have a clear path there, instead of letting people imagine "we will have a PCB and software running on it, how hard can that be" and kickstart that. (because most electronics products are "straightforward to get manufactured" at some level, getting there and not overcomplicating it so it isn't anymore is the problem)
