But more likely is twisted creativity. It seems that some businesses are still using ancient systems, based on COBOL, AS/400, etc. There's resistance to changing legacy code. So when business changes require additional data fields, fields sometimes get subdivided. So a field that originally contained stuff like |foo| now contains stuff like |"foo","bar,baz"| or whatever. That works, because there's nothing like CSV in the data system. But when someone tries a CSV export, you get garbage.
