The thing you need to understand about Oracle is that it's never — well, never in my experience, and I've worked as a DBA (mostly postgres, but I have had my hands on some Oracle) for a decade now — chosen by the technologists. It's chosen by management. Usually non-technical management. Often dangerously so.

But Oracle support basically doesn't answer the phone unless you're regularly cutting them six-figure checks, so you kinda need that level of management to be making the decision whether or not to use the platform.
