Perhaps "sales" and "poor" aren't the best terms at this point. I am surprised that their loyal customers don't cover this cost entirely, though, and maybe they will.
Since this is, in effect, an attempt to raise venture-capital (a long-time common practice - even a li'l company called Intel did this), I wonder if donor/investors need to be indemnified against future lawsuits?
In Sep-Oct 2012, DVDRanger claimed their original Cinavia-defeating product development had been stopped due to some vague unnamed, unspecified lawsuit brought on by unnamed parties in some unspecified court system.
DVDRanger said they'd return 'pre-sales money' to anyone who asked. Since their forum is private, there's no way to tell how successful those claimants were back then.
Of late, DVDRanger announced this new CinEx product's development, but hasn't addressed its likely success against the same potential for a lawsuit that could halt development again.
So, does a donor now need to show due diligence before donating/investing? Do donor-investors need to be worried about contributing to an effort that would lead to a lawsuit? Do donors-investors need to worry about being dragged thru some nebulus court system for their contributory part of 'development'?
When simple questions aren't addressed, then more complicated issues seem to arise.
