I agree with you, but I'd like to point out that the article was expressing apprehension at hiring the guy (e.g.: he was concerned as to whether he'd be able to keep him employed for more than 2 months)... there's no indication that the financial state of the company was hidden from the employee.

At least in my experience, while I haven't known the exact financial state of startups I've worked for, I've generally known the level of risk I was signing up for.
