tl;dr – they’re all scared of being hacked

“The Dissident” is not the only political documentary that has failed to secure a home on a streaming service. This year, Magnolia Pictures, which has a streaming deal with Disney-owned Hulu, backed out of a deal with the makers of the documentary “The Assassins,” which tells the story of the poisoning of Kim Jong-nam, the half brother of the North Korean leader Kim Jong-un.
The film’s director, Ryan White, referred to the 2014 hack of Sony Pictures in an interview with Variety, and chalked up the “bumpy road” of U.S. distribution to corporations feeling they “could be hacked in a way that could be devastating to them or their bottom line.”
