Shorts are selfish beings: they buy stocks in the form of futures, in order to be able to cash in when the stock drops in value. Basically they are trying to drop a wrench in the machinery of honest manufacturing, in order to delay or thwart a given company's efforts to make a better world.
But the shorts will lose out in the end: if humanity votes with their wallets, in the way they are doing with Tesla, the number of electric cars will exponentially grow despite efforts to delay this. Because the humans are deciding on a bigger scale that the electric revolution needs to happen, the shorting organisms can be made to do what mankind wishes to happen, or they will perish as the stock keeps going up despite their efforts.
