Despite that, I think that it is correct to see this as a battle between closed and open in the important sense that Oracle clearly does not give a jot or tittle about the open source community, and Google does, albeit for self-interested reasons. Oracle's attitude can be gleaned from two key facts.
First, the extreme terseness of Oracle's press release announcing this lawsuit, quoted at the start of this post, makes no effort whatsoever to soften the blow as far as open source is concerned. Had Oracle cared, it would have made soothing -- and admittedly pretty worthless -- noises about not wishing to damage the open source community of Java hackers, and how important they were, and how regrettable it was that they would be innocent victims of wicked Google's naughty, naughty actions. Instead, we have zilch: Oracle just doesn't care what happens to the open source ecosytem that has grown up around Java -- and it doesn't even try to hide the fact.
Now, it might be argued that this is only the initial press release, and that Oracle might issue further ones clarifying its position, and softening the blow etc. etc. In response to which I offer Exhibit B:
OpenSolaris is Dead.
What follows is an email sent internally to Oracle Solaris Engineers which describes Oracle's true intentions toward the OpenSolaris project and the future of Oracle Solaris.
This concludes over four years that I (and many other external contributors) have worked on the OpenSolaris project. This is a terrible sendoff for countless hours of work - for quality software which will now ship as an Oracle product that we (the original authors) can no longer obtain on an unrestricted basis.
I can only maintain that the software we worked on was for the betterment of all, not for any one company's bottom line. This is truly a perversion of the open source spirit.
If Oracle really cared about OpenSolaris, it wouldn't have done this at all. But accepting that it had to make a possibly hard decision about ceasing to support OpenSolaris, it could have done it better in so many ways: offering its regrets and best wishes for the future, smoothing the transition to an external project, etc. etc. But no, the news creeps out as an unimportant aside - and on the very day that Oracle launches its lawsuit against Google.
