I see it as simply a domineering act on the part of Oracle
"We own Java" is the message they seek to convey. Unfortunately, they may well not be the best stewards of the Java core API and broader library base - but time will tell whether any presently unknown circumstances may eventually serve to resolve that.
The FSF's response, I'm afraid, is merely an attempt at piggybacking their own agenda onto the fundamental issues being actually called into light, with the lawsuit.
Don't get me wrong, I love the principles embodied of successful free open-source software projects, such as the Linux kernel and the broader base of true-to-FOSS-principles Linux distributions (including Ubuntu). I'm sure that the approaches that the said projects have taken, to their successes, would not have included:: Conflation of principally unrelated issues, however.
I feel that I can say that in good conscience, though I'm not personally aware of the exacting details of the lawsuit - such details that will have to be addressed, towards any useful end (or not) in the courts.
As far as predicting Google's next move: I wonder if the lawsuit would disappear, if Google was to simply agree to license an Oracle-branded Java release, for release - in turn - on all Android platforms? Surely, Ovrakill could've taken another approach to as much - any approach becoming to actual friendly business relations, for instance - *if* they would recognize that objective, in the matters.
Maybe Google can still actually save the situation, by giving the bully some scrap of their lunch, already.
I'm sure that calmer heads may yet prevail, about the matters.
Now, a beer for all the platitudes. Cheers.
