I suspect its because having a personality lead company implies that people buying that product tend to agree with the personality. Tesla is an extreme example, Elon is either Jesus, or Judas. There is no in between. I have a Powerewall, because it was at the time the best product. When I do talk about it, the second or third question is: "what do you think of, you know, nod, nod, wink, wink". He's a polarising figure, which makes getting useful reviews out of their products/business practices hard. (same with Facebook, Nestle and other pariahs.)
