I love to mock this hopium dream as much as any grounded cynic, but frankly, I don't think these people are entitled to refunds. There is no conceivable way the crowdfunding model will work if the company, at any time, is vulnerable to essentially a bank run. I'd rather see adults held accountable for their actions: if someone on the internet convinces you to give them $ and they'll make something cool, and they fail to make something you think is cool, you aren't likely to get your $ back. Perhaps more importantly, I don't think you're entitled to itif a valid attempt was made to see the project through.
Regardless of SCO's ultimate fate, I don't think anyone would deny that they're trying.
