CNET may be owned by CBS, but they totally gutted staff quite a while ago. The "article" was written by a "blogger" who "brings an irreverent, sarcastic, and sometimes ironic voice to the tech world" and "is not an employee of CNET."
Not sure where you reached the conclusion (from the article) that Nissan dropped LA based on FDA and/or whistleblower legal issues.
The thing that we are seeing is that many info sources (credible/established, bloggers, whoever) are becoming more aware of LA's current issues and that will be appearing in many articles/blogs/WWN/etc.
My issue is that the CNET article reference has no basis in fact - the author is tossing out a joke based on the LA debacle popping up in the current public consciousness.
"Nissan certainly appears to have taken that step" - as far as I interpret that statement, it appears to be unsubstantiated by anything at this point. "Appears" is definitely an opinion; I myself would base an opinion on that issue on more than a blogger puff piece.
