Just two days ago this NYT editorial [1] was on the front page of HN with 20+ upvotes IIRC, and before there were more than 1 or 2 comments the post was deleted and unviewable. (And didn't show up as flagged either -- just totally deleted.)
I'm not sure how many people on HN are aware of what appears to be admin censorship of this topic. And it's not like it's some incendiary blog post -- it's an Op-Ed from the nation's traditional "newspaper of record", part of the national conversation, and relevant to our industry.
