Lucky you. Sadly, not all companies are new enough to be able to do that. Some embarked on Java when it was Sun, and Oracle when the only alternative would have been SQL Server (or DB2 on AIX, AS/400, or MVS).
Their software wasn't just more expensive than using open source equivalents it was worse, too. It's just very, very sticky.
At the same time the sales team wine and dine key decision makers and try to strike the fear of god in to them so they don't rock the boat.
