They'd spend quite a bit of their social capital with the Linux community if they tried to be private that way.
I've also heard rumblings that a primary motivator behind the CDDL (and GPL incompatibility) was a core group of old Solaris devs at Sun that would have been royally pissed off if their work was GPLed. I wonder if Oracle would care if they quit en masse.
I don't think Oracle really believes there's value in "social capital". To the contrary, they seem to thrive on the fact that almost everybody despises them a little bit. If people were happy to do business with Oracle then Oracle would feel like they weren't charging enough.
