My guess is because people regard the shotgun questionnaire as a rhetorical tactic that burdens the responder with having to extrapolate the intended position that the questions are written to draw out, while simultaneously leaving a vacuum of supporting arguments to justify the analogies explored by the questions, as if the implied argument is so rock-solid that it requires no bolstering, convincing or exposition. This effect is compounded by the fact that some of the questions are clearly poor comparisons (e.g. the comparison between an organization that chooses to filter content within the confines of its network vs an ISP monopoly restricting a paying customer's access to legal content - no matter which way you come down on the question, they are clearly totally different scenarios)
