FUD inflicts temporary damage (which is why the FUDsters are active), but I disagree that it's irreversible, because most of the FUD is shallow and self-defeating against just a little bit of exposure to a Tesla product.
This can be seen in yesterday's episode of Tesla trolls descending on Cheryl Crow when her Model 3's screen went dark, to which in the end she responded:
Sheryl Crow on Twitter
"Problem solved! LOVED all of your creative responses. Best one was suggesting my kids take a look... which would have been helpful since my kid was the one who changed the settings / caused it to go black in the first place! I knew I should have interrupted school..."
"
Also, for the haters: I love my @tesla, and have very few problems. I got the basic model, nothing overly fancy, and it was cheaper than my minivan!"
These are powerful testimonials from owners, and while it's slower than
buying favorable media treatment, it demonstrates that the FUD is not irreversible.
There were a lot of Apple haters as well when iPhone market share was still small and growing, and media treatment of Apple was dominantly unfair and biased as well - despite Steve Jobs communicating in an almost picture-perfect way. There's just no pleasing of biased observers if attacking a company is in their financial self-interest.
