I also like Elon, but the source of the hate probably comes from two sources. The first is the audaciousness of his general proposal: that we give up technology that worked for a century (oil) and try to build something entirely different. It's based on a bias towards the status quo.
The second is probably more legitimate. No question Tesla has done amazing things, but is it really worth more than established players that sell 10X number of cars? The stock price doesn't make sense based on any traditional valuation, it can only be explained by popular enthusiasm and exuberance towards the vision that Elon provides. It feels to many that Elon is getting away with things that would doom any other company because of this perception. It feels unfair, hence the haters.
Personally, I do love Elon, SpaceX, Tesla, etc, but I don't want to get involved in the stock market casino. I support what he does because of his vision, but Tesla's stock price makes no sense to me. Instead, I'll cheer from the sidelines, and invest my money in boring ETFs.
