I'm not entirely sure I agree... It would seem like advertising their new releases would be a selling point for their service. And their movie "new this week" listings seem to be up to date. I'm more inclined to blame the lack of complete TV new release information as incompetence / inattention on their part than as part of some intentional plan.
But I'm open to learning other opinions. IS there a way it helps their interests to be ...discrete?... about some of the new releases? I'm curious!
