I agree & I add: - some components of their EPM-software-suite have miserable error/warning/info messages (cryptic, misleading, etc) or even no message at all (making you erroneously think that doing something went well even if it did not). - opening a "service request" (a support ticket) with Oracle when you have a real technical problem that needs active digging by them is often something that might make you regret having chosen IT as your work area. Compared to that, once I'm done working and I go back home and start using Linux apps and/or submitting questions&bugs on github/linuxquestions/stackoverflow/etc and getting relatively good replies within minutes I get the feeling that I'm living in the year 3000 :)
