You have basically found the Reddit /r/technology contingency. Most stories I see there are laughing at a single man's failures. There's just a lot of hate. I wanted a Tesla because other friends and family let me ride in theirs. I liked the car. I also like Chick-fil-a Chicken, and Papa Johns Pizza. From time to time, I visit Hobby Lobby. If I did digging on EVERY CEO, and found things that I disagreed with, I'd likely have few places left to shop. Instead, I try to focus on the other "non-crazy" folks that work at these places.
When it comes to Tesla technology... it's actually really good.
I don't know anything about r/technology, but I do know that Musk has alienated his core customer base, and is continually making massive noise about politics, unlike most other CEOs. And even more stupidly, he is aligning with an anti-EV, anti-solar, anti-energy storage political faction in his attempt to alienate early adopters. Makes him seem extremely weak and self-hating.
And that's before all the bad decisions in the direction of the product over the past six years. Musk's made a great product far worse by being so involved and making boldly bad decisions left and right.
