It would have been nice to include a little, more personal, summary. Something like:

Edit: the original parent said that the tone of the Tesla posts seem defensive. I'm not really sure what was wrong about the comment... they do seem a little defensive in tone. (Often understandably so...)
Oops, I deleted the comment you were replying to, because I thought it came across a bit too negative. It essentially said that they always come across very defensive, compared to tech company post-mortems that try to be very factual.
