Every company I've ever worked at had roughly 50/50 amazing and terrible code. The larger a codebase at a company gets the more likely that there will be code in there that is _just_ good enough and no more. Polish and other elements of excellent code cost money and time to produce. It doesn't always make sense to invest the necessary money and time into it. Sometimes quick and dirty is literally the correct decision to make from a business standpoint.
