It has been suggested several times on HN that another reason is that it attracts younger coders. Younger coders tend to be more willing to just follow the lead of the management, rather than ask "is this really going to solve the problem?" Younger coders will put in massively more hours -- this may result in problems like reinventing the wheel, piles of garbage code, etc. -- but it generally "feels good" to be the manager with an energetic, 24-hour around the clock team of young coders. Younger coders can be paid less, and are willing to forego benefits, stability, medical plans, or even pay sometimes.
