I frequently wonder about why so much hate on Arthur Hayes?

I understand that he is a central figure and spokesman for Bitmex, yet it seems that Bitmex has uniquely contributed to the liquidity of the cryptospace - bitcoin and various alts by providing a platform to short a lot of alts that would not otherwise be able to short.  I am fairly sure that his platform provides a vehicle for manipulation, and yeah, sometimes there are claims of internal exchange shenanigans.  Bitmex profits from exchange volume (and probably has profited immensely just from the kind of service that they have provided to the space), and I don't see why they would want to additionally manipulate with insider shenanigans to ruin their reputation, because they are already making a killing just from regular business.  Also, they have provided some really decent research articles in the past couple of years.
