A business still needs to hire people to work on Oracle db. At my company they have trouble hiring for it. They resort to shared service orgs to provide DBA services. That means one DBA per 10-100 application developers. It’s awful. We do anything to avoid oracle because we can’t get a DBA to help us. Even use hadoop hive for non hive use cases.

I guess my point is that these struggles eventually do reach the leaders and they choose something else. We moved off teradata because of shared service orgs so we'll probably leave this type of oracle at some point too. Either a completely self service option of oracle or an open source one.
