The Tesla story is interesting to 'good hackers' because it is a company that does exactly the kind of thing that 'good hackers' love to read about: disrupt a bunch of incumbents. The fact that Elon Musk started out as a nobody that came to the United States in order to chase his dreams and is actually doing just that coupled with the fact that I suspect that a large number of HN readers either has a position in Tesla and/or drives a Tesla (or covets one) means there is a pretty good chance that substantial articles about Tesla will get upvoted.
If you can't deal with that rather than telling the people here to go elsewhere maybe you should go elsewhere or at least attempt to add to the discussion in some constructive way.
