My unscientific observation is the Tesla criticism is basically Elon Musk criticism, and most of that is from people who are either jealous of his accomplishments or ideologically opposed to him politically. The jealousy ones are clickbait articles denigrating him in one form or fashion. He has has plenty of legitimate criticism levied at him, but much of it is jealousy intended to soothe the ego's of somone who simply can't abide the success of another.
