The Jalopnik post has been updated with a statement from Tesla saying that the battery will take a long time to reach zero state of charge. My understanding is that the battery system will protect the battery during normal use but that there isn't much it can do if the car is left sitting unplugged.

So the 'confront misinformation with facts' tone of this article ends up being a little over the top, the blogger is interpreting the facts differently than even Tesla.
