It is political. That's not even really debatable.
> Press freedom is a much more fundamental issue than political affiliation.
Maybe, but that doesn't make it not a political issue.
> Much of the discussion that has been suppressed by mods on HN has had to with the knee-jerk characterization of stories like this as political.
This story is one “relating to the government or public affairs of a country”. It is, therefore, squarely political.
This story is also badly distorted and hyperbolic; most of the things at issue were done to mainstream reporters before they were done to WikiLeaks, especially including investigating attempts to get and reveal classified information as potential espionage or conspiracy related to espionage, and not giving reporters advance notice of surveillance related to investigations in which the reporter or the people they were communicating with were subjects or targets. (Notifying the subjects and targets of surveillance of the surveillance tends to be counterproductive.)
> HN mods have shown a strong pro-authoritarian sentiment
Support for this inflammatory claim is called for here.
