It's possible that if they're trying to sell the company, that they want to keep as much of their stuff (SDK, etc) as secret as possible since, to a business person, this may represent value. This sounds totally warped, and it's difficult to believe that anyone so ignorant of the actual maket could run a business (or, at least, invest in a business) in this field, but I've seen things like that happen. Companies with this sort of attitude frequently fail, of course.
