You are correct on the third reason. In fact, one compny that I follow was trying to do just that last year and I was in favor of it. Many investors on this forum were against it because they thought that their shares would be diluted. But if they do not have money, your shares mean nothing. Doing the RS would guarantee that company would have had cash to fund operations for several years. But now, the company, after changing their minds, are facing just a few more quarters before they run out of cash.
People need to get over this dilution thing because it renders them unable to think rationally. They would rather lose everything than make less than they originally thought.
