Well, it was dripping with sarcasm, and they did call him out by name, and then accused him of being a short. That might be true, but the tone is not really what I would expect as a professional response by a major auto company. I would have expected something more along the lines of "the original blogger did not report all the facts correctly and Tesla strongly disagrees with his conclusions" or similar. Not this whole rant:
Finally, it is worth noting that the blogger who fabricated this issue, which then caused negative and incorrect news to be written about Tesla by reputable institutions, is Edward Niedermeyer. This is the same gentle soul who previously wrote a blog titled “Tesla Death Watch,” which starting on May 19, 2008 was counting the days until Tesla’s death. It has now been 2,944 days. We just checked our pulse and, much to his chagrin, appear to be alive. It is probably wise to take Mr. Niedermeyer’s words with at least a small grain of salt.
We don’t know if Mr. Niedermeyer’s motivation is simply to set a world record for axe-grinding or whether he or his associates have something financial to gain by negatively affecting Tesla’s stock price, but it is important to highlight that there are several billion dollars in short sale bets against Tesla. This means that there is a strong financial incentive to greatly amplify minor issues and to create false issues from whole cloth.
They should have taken the high road, not the low one.
