This is a very anti-Musk thread and generally anti-Musk crowd. Pro-Musk comments should be expected to be downvoted, unfortunately. It's days like these one has to be brave and burn some magical internet karma points in order to present an opposing view and to call out the one-sided discussions.
I don't think the comment is being voted because it's "pro-Musk", but because no one believes they're going to do any of that. I even thought it was a joke, until they asked why they were being downvoted.
The true is, there's a huge gap between what was promised early on and what they seem to be able to do. After a certain point people start calling it "bs" and have no patience for those repeating the initial claims.
