Dev Bootcamp.. why it did not succeed?

Saw this story today. Dev Bootcamp, a software developer training company, is shutting down.

When I first heard about it in the news I was like, "dang, why am I not doing a business like this." It would be an awesome thing to do. Look, there is the need... people need skills and updating their skills. Sure, you can get tutorials for just about everything out there. But it is much much more effective if you have a live instructor and some fun projects to work on, and you get to work with classmates that's even better. That university classes are too expensive! (and you actually don't get much) I think there will be people who want to learn a thing or two without paying too big a fortune.

I don't quite understand this line: "(D)espite tremendous efforts from a lot of talented people, we’ve determined that we simply can’t achieve a sustainable business model without compromising our mission of delivering a high-quality coding education that is accessible to a diverse population of students,”

I don't understand this line either: Just what is this microscope? "Coding schools have been under increasing pressure in recent years, as for-profit schools go under the microscope nationwide and coding schools attempt to prove their worth"

So what is the issue here? no one sign up? why? too expensive or no one wants to learn? BTW, too many programming jobs are going overseas... perhaps even the most skillful developer would have trouble making a living.

There is gotta be a way to run a successful training business.
