I'm not sure how you came to the conclusion that this is torture porn. The way the characters behave, especially Phlox, is consistent with what we've seen of the Mirror Universe. I think that the story's title is supposed to be Hostile Defiant Takeover and that it's a misspelling like there are a few in the story itself.
I could be wrong but I don't see any reference to the movie 'Hostel' in the story.
