Don't think they are short-sellers except for a very few who can back their words.
They either don't understand what's really going on or they missed the boat hence very salty. Either way the trolls don't have the conviction to short-selling I'm pretty sure.
They don't have the courage and mind to make a call in the market / innovative business and end up stuck in the value trap mistaken as being 'safe'...
