The problem is that what you just described is a Ponzi scheme, and those tend not to work out very well. My gut feeling is that someone - most likely an insider - made off with their float. That would include all of their cash in the bank, their BTC, etc. that they had for operating the business, plus all customer funds that happened to be in on that day. As long as new money keeps coming in, they'll be able to keep the charade up, but I have never heard of one of these things lasting, and it appears that the natives are getting restless. My guess is that the massive delays have caused the flow of new money to dwindle, which means that this thing is coming to an end sooner than later. The email they sent yesterday is a pretty good indication that they have or are about to reach their breaking point.
Why a Ponzi? If Ford Motors had a support board somewhere it'd look the same, people coming in with complaints, complaints getting resolved, new people coming in with new (or rehashed old) complaints.
Your theory seems highly speculative.
Funding old orders that you couldn't deliver with money from new orders (that you won't be able to deliver unless and until further new orders come in) is the very definition of a Ponzi scheme. They last until new orders stop or slow, as is beginning to happen here. Then it all comes crashing down.
