Many commercial databases are good and work very well. The difference is when you are stuck with a small ridiculous problem and are cash-strapped and in a hurry. Google searches turn up far many more results for solutions to OS software problems than for commercial products. Also forums, knowledge bases and communities are not that convenient to access for many of the "enterprise" vendors. Finally there is the issue of the eventual price being "call-us" for many commercial solutions (although it seems like it is not the case here with DB2). Open source products often just better fit the dynamics I'm in when starting something.
