Rupert Murdoch does not own the Guardian. That is laughable. It's owned by The Scott Trust Limited, which was formerly a charitable trust and is dedicated to keeping the Guardian's editorial independence.
The original posted news story was by a Murdoch-owned newspaper; has since been changed to the Guardian (possibly while OP was writing this equation?). So the equation kind of holds, just drop the Guardian but.
Of course Oracle published this to damage Google, that's obvious. But that doesn't mean the claims are untrue. It's likely that there's something to it, even if the amount of data is incorrect.
