Most 'enterprisey' systems of the era were just as shoddy as Horizon. The problem was that the post office were in a position to aggressively prosecute users and decided to do so (and then the whole chain of cover ups and dissembling for years after as widely documented). All in all its a lesson in just how easy it is to cover your arse as an executive in a large company, and get away with pretty much anything. Only the most tenacious work by many people over decades has any chance of holding you accountable.
