'freerobby had a good point, somewhere up the thread. I regret taking part in your inane and patronizing distraction from that.
The fact that it doesn't happen should tell you that it's not such a clever idea as it might naively seem. And I just gave one example of how such a strategy could back-fire, by attracting long term investors who like to buy at discounted prices.
The examples you gave don't fit the model. They are all profitable, they do not constitute an existential threat as Tesla does to big oil, and the relative differences in market cap is nowhere near as big between the parties. It's hard to overstate the proportions here -- the entire $12B of short interest in Tesla represents less than 2% of the Big Oil market cap. And that's without touching Aerospace/foreign governments that might want to starve SpaceX by way of Tesla.
