I'd say you shouldn't just write that off as a freak incident though. You should be reconsidering how you read these kind of job adverts - obviously, a company can succeed even with this kind of approach - and it can obviously fail with it.
That means that the language or style used to convey a job opening is probably NOT a good indicator of the success of a company. Maybe it's time to rethink prejudices?
Sure, it's not a good indicator of success, but it generally is a good indicator for what kind of people you'll be dealing with and how you will be communicating with them.
Depending on what you want, of course, you should look for different things. I'm not going to make the judgment call on whether a company will be wildly successful - I don't have the background for that. I'll see if they have any chance of surviving and if they do, if it would be a pleasant environment to work in.
