Add a way to indicate that an article is pay walled before you ban talking about it. Otherwise you are just trying to police people from talking about the elephant in the room.
It isn't the elephant in the room. It's been the status quo for as long as HN has existed. You could hardly find more common publications here than the NYT.
The objections seem to be largely ideological, and reciting ideology is the essence of uninteresting in HN's sense. If someone comes up with something new and clever to say about paywalls, by all means post it as a story and let the community have at it. Repeating complaints for the zillionth time, not so much.
