Shorting Tesla Stock Was Big Business
Ifs easy to forget that prior to Tesla sorting out its production problems resulting in the current lofty (unrealistic/fantastic/overblown -- you name it) stock valuation Tesla stock was a favorite for short sellers. There was a lot of big money shorting this stock so any news -- real, speculative or just plain fabricated -- was welcome news to these sellers. Tesla jumped on this kind of whistleblower because its the sort of thing that could snowball.
The story behind the story is that currently corporate performance is reported solely in terms of how it affects that company's stock price. This is a logical outcome from the wholesale adoption of Milton Freidman's theory that the one and only purpose of corporate management was to "deliver maximum value to shareholders" -- the stock price is all that matters. This might not be important if your corporation is an effective monopoly, you control the message as well as the product (until things really start to go South like airliners start crashing**) but if you're trying to develop new product like Tesla the stock market will kill you if it thinks its the quick way to make the money.
