You only think your are free (and open)!!
It's Oracle, so you knew this dog-bites-man story was coming in some form. Big proprietary software company buys signficant open-source assets and starts to rather ruthlessly monetize them. How much do you want to bet that in the future, Oracle's salesforce will only be pushing branded Hudson tools.
I'm not even saying that this is necessarily wrong if you can provide a superior customer experience with the branded products, but its definitely not real open-source.
Big brother, because he looks more like Larry Ellison than the evil Gates and Evil Jobs icons.
