Longs make up utter bullsh*t all day long on CNBC and Twitter, and Prem has made up a whole bunch of his own, so this whole idea that short sellers are some unique demon is nonsense. Even if MW is incomplete, he's allowed to go out there and say, with a great deal of backup "Here's why I'm short". If he's wrong he'll eventually go out of business. But he's called out a LOT of bad actors in his time (no, he hasn't batted 1.000 - have you?) and Fairfax is not some innocent lamb. If shorts are out there getting "100 wrong for every 1 right"
A. No one would trust them and B. They'd lose a lot of money fast.
Chanos is a good example - he made a career out of calling out bad accounting and bad actors, but in the end the totality of his analysis wasn't good enough so he went out of business. Prem has been wrong again and again, and publicly so - why is Chanos the bad guy?
Bulls don't get a monopoly on the microphone.
