The more charitable and more likely reading is poking fun at a CEO's hatred of people who bet against the CEO's company. Perhaps try re-reading that way?

Sure, but we're not talking about the vast majority. We're talking about the most heavily shorted stock on a US exchange, and the one which entrenched players are most interested in seeing fail. Tesla is an outlier in myriad ways; deriving assumptions from the median makes no sense at all.
However, Tesla does not need to be exceptional for the larger point to remain. Former heavily shorted companies have dealt with the same thing. Look at the war between Fairfax and hedge funds in the early 00s (similar claims, similarly evidence (i.e. circumstantial but unprovable), similar results (stock took hits and then jumped as financials improved).

Someone at TMC wrote up a more thorough and Tesla-analogous explanation if you are curious: https://teslamotorsclub.com/tmc/threads/elon-musk-vs-short-s...
Why would they be?
