I voted for it before reading it - it sucks. The title makes it sound like Glenn Greenwald is saying sorry - I don't see anything like that in there. His name gets a couple of mentions, but it's about some no-name former marine changing /his/ mind. I regret my upvote.

edit: Ah, I mis-read the title, I see he's saying sorry to Glenn Greenwald. No harm no foul, but I still wouldn't have upvoted.
