Unfortunately they need money for research and components. If they had that money, they'd just build the machines and mine themselves. So to fund the research and components, they solicit pre-orders. Yes, it sucks. But I don't see a way around it... ?
I do, it's called getting investors. bank loans, crowdsourcing, etc. Draw up a business plan and present it. With the history cryptocurrency device manufacturers have had (BFL, BitFury, KNC, etc) you should be able to easily show that there is a demand. If all else fails, go to Kickstarter.
You must mean crowdfunding not crowdsourcing. Taking pre-orders is basically crowdfunding, and we are the target crowd. Kickstarter is usually for charity, it's for donating, I don't know why people would donate to a for-profit business. But still, it would be nice to not have to gamble on a pre-order.
