20 years of working with Oracle RDBMS and I recently climbed out of the dark hole and saw the light that is SQL Server, MongoDB, Maria, PostgreSQL and even little SQLite, a whole world of fun DBs to play with. Oracle will happily keep fleecing people all the time they keep paying, but they're a hydra that's slowly being hacked to pieces and losing heads, one day the reckoning will come and it's not too far off.
The world is changing, a new breed of IT people are coming into the workforce that won't simply accept the way it was, some of the old guard like me are willing to go with them into a future with a lot more choice. Oracle have had their day, now it's time to retire, they know it but they just won't accept it.
