I can't speak for him but: With titles like: Hertz is selling Tesla's cheap, or Musk says Tesla dug their own grave, or Drape your EV in a fire blanket if you park it in your garage, etc, etc, it catches my eye. Even though I don't like them, and won't own one I read about them, and learn. I love to learn, even about things I don't like, so I can converse about the topic with friends or family. You see I love cars, and love to talk with fellow enthusiasts, like my doctor who sold his Tesla and went back to ICE. We had a great conversation a while back. I learned a ton about EV's by reading, granted I would not join an EV forum!
There are certain people in high places I don't like either but if they say or do something that might impact me I read or watch the segment. Now if the EV section was at the bottom of the forum, and not in the position it's in, it wouldn't catch my attention as much, and I'd participate less in it. I'm sure that would be the same for other members too.
