One overlooked aspect is the career prospects for someone in IT working with an Oracle system. It is a network effect where career prospects dictate the system chosen which in turn makes the system more prevalent. Soon they are known as someone who has overseen an installation/maintenance of an Oracle system and can look forward to a stable career. In contrast someone installing a postgres system will not have the same opportunities.

It is a similar dynamic with SAP another much detested system by everyone who is not in IT or works as a consultant. It is amazing to me, pretty much everyone who actually works in an SAP (or Oracle) system detests it but cannot get IT to provide an alternative.
