That seems analogous to the "atheism is a religion" fallacy. No, not wanting to see politics in one very specific location is clearly not a political stance.

Where does "politics" end, then? What about articles pointing out a tech company's ethical wrongdoing? Or about their legal troubles? How about the technology behind war fighting drones? Or software's role in mass surveillance, war crimes and ethnic cleansing? Are these all off limits because they are inherently political? By banning these and similar topics, HN's purpose becomes more and more about whitewashing the industry and less and less about honest discussion.
