This is the aspect that baffles me. I've heard people say with a straight face that they'd prefer to use Oracle "so there's somebody to sue" if things go wrong.

But it also seems to be uncontroversial that no good could plausibly come out of attempting to sue Oracle.

Good question. I don't know.

You have to live with them anyway?

You obviously don't try to sue them, their company is 90% legal staff [0]. (Sorry I can't find the original source)
