"That is the sorry reality of the bazaar Raymond praised in his book: a pile of old festering hacks, endlessly copied and pasted by a clueless generation of IT "professionals" who wouldn't recognize sound IT architecture if you hit them over the head with it. It is hard to believe today, but under this embarrassing mess lies the ruins of the beautiful cathedral of Unix, deservedly famous for its simplicity of design, its economy of features, and its elegance of execution. (Sic transit gloria mundi, etc.)"
The real problem is that in "business" instead of the bazaar, you often don't have the time to design something the "right" way because of "business requirements," so you end up in the same mess.
