The reddit comment pavanky links to (by Natedogg213) does a pretty good job pointing out the fact that this story simply isn't true, and is really just another case of lazy "mainstream media sux" claims. I'd like to add something from the other end:
Yes, it's true that this snowden interview wasn't well-reported on. It certainly wasn't blacked out, or suppressed, or whatever, but editors must not have considered it front-page material. That's because it /isn't/.
On days when HN collectively has its wits about it, we're lamenting the fact that too much journalism has focused on Snowden himself, and not enough on the important stories: what was revealed, how the NSA responded, how representatives (collectively and individually), and what the likely political future is for a reform bill. These are stories that give voters important and interesting information, and they tend to be very well covered. This interview doesn't reveal interesting new information in these areas.
