The crux of the matter is:

"...The business jet market overall is also entering a period in which demand is expected to contract sharply in the near term, cutting sales for every participant in the VLJ market..."

When the economy is down, spending on premium services such as air taxi services will be down as well.

Eclipse represents a sign of the times in the present age. They had a great product with the first VLJ, and a strong business model based on good reasoning, but one which requires a strong climate in which to succeed. The gamble Eclipse made was for an economy that would hold up long enough to sell the jets it had on backlog as pre-orders while it progressed into "economies of scale" as the venture matured. There was a host of teething pains as we know, Vern Rabun's departure as an example; but the real danger for Eclipse was the downturned economy which represented an inescapable death sentence because luxury items go south when people are worried about cash. It will be a miracle if the company survives at this point. The lesson is that anyone can make a good airplane, but only the truly fortunate can make one that is truly successful.
