His response took a bad review and turned it into front-page news in a way that would not have happened if Tesla's response hadn't been combative.
The reason the author wrote this post is to educate you, startup founders, that Musk's tactic was dumb. Tesla will survive it; Musk can afford to pick fights that raise awareness of Tesla's negatives. But you probably can't afford that for your own company.
You can respond to this post with yet another 10,000 word thread about who's more credible, Musk or Broder, but to do so is to miss the core point of the post.
