making negative comments about Elon Musk.
I've seen this as well. Boiling it down, my perception is that Elon Musk is honestly concerned about how people receive his product. If you have a genuine problem he'll attempt to make it better. After all, somebody tweeted him*, he then went through the effort(or made somebody else do it) to track down the reviewer's car, complete a more extensive diagnosis on it(failed battery) and send a team out to fix it. We don't honestly know whether or not this was due to the public perception, though the article writer notes that he's not the only one reporting on the forums that they're replacing the batteries. He does mention that the 60kwh version is having more problems reported, which is indeed a head-scratcher, but it could be a perception thing - 60kwh owners could be more concerned with efficiency than those that buy the 85kwh vehicles, after all.
Now he DOES get incredibly pissed if you misrepresent his product - see the lawsuits against Top Gear for implying the vehicle ran out of power and had to be pushed into the warehouse, as well as firing back against the NYT author who drove faster than he said, ran the heater/AC when he said he didn't, deliberately missed charging points, disconnected early and did loops around a parking lot until it died.
So a guy makes an honest assessment and Elon gets his car fixed. Somebody lies and he sues. Sounds like he has pride in his product.
*He has to be aware of the problem before he can fix it, of course.
