I came across this quote [pdf] today, from 2006 doing some research. From TFA:
Q: Why isn't Oracle a member of the OSDL?
A. ... We basically know where to go. We have a good relationship directly with people in the Linux community. We have all our partners. So there is no immediate advantage to being a member for us.
Not to sound arrogant, but we know how to deal with the Linux community
Gotcha, Wim ... 'does not play well with others'
... in a related vein, I cannot remember the last time I heard an Oracle representative on the weekly LSB conference call
